Omega review

  I was looking for a new pistol mounted red dot to install on my Rost Martin. I knew I wanted a larger window size reflex sight for that pistol. So I did what any good reviewer would do and hit up the good people at Gideon Optics. Gideon had just what I was looking for in their Omega series. When they asked which version I wanted to review, I said the green dot only version. So a few weeks later I received it. That is where the story takes a twist.

  The Gideon Omega arrived at the perfect time. I had just received a lightweight 10/22 kit and it needed a lightweight dot. So even though I had intentions of mounting the Omega on the Rost Martin, it proceeded to get mounted on the 10/22 with the CP Firearms Dragonfly kit. The Omega was perfect for it. Its large window lets you see the dot quickly on this little rifle. Plus the Omega came with a pic rail adapter already installed, so all I had to do was tighten it on the rail. The Gideon Omega has an RMR footprint so it will fit on a ton of pistols cut for an RMR optic. Which is exactly what I originally had planned for the Omega.

  Gideon Optics has hit the ground hard with the Omega. It is their larger window RMR footprint reflex sight. The window size is 0.88 inches tall x 1.06 inches wide and round shaped with a flat on the bottom. I found it extremely easy to pick up the dot in the Omega. Probably because round objects draw the human eye to the center. Having an RMR footprint makes the Omega very versatile. There are so many mounting options for it, either direct or some sort of picatinny mount. Even offset style mounts can be had with RMR footprints.

  For this review, I asked for a green dot version of the Gideon Omega. It also can be had with a red dot, a red circle dot, or a green circle dot. The dot versions have a 3 moa sized dot and the circle dot versions have a 45 moa outer ring with a 3 moa dot inside the ring. I chose the 3 moa green dot because green is usually clearer for me. I also am not a fan of circle dot reticles on pistols, even though some people love them. The dot is bright enough to see on a hot summer day with zero clouds in the sky. The Omega has 10 brightness levels in case you need to turn the brightness down, 2 of those are night vision compatible. I am also a big fan of being able to set the brightness where I want it. I am also pleased with the clarity of the green dot. It just does not star out like a lot of red colored ones do for me. The dot was easy to pick up and super fast on that little lightweight 22.

  Auto on and off is a feature every new optic should have. The Gideon Omega has this auto on/off feature. Essentially, when you move the sight, it automatically turns back on to whatever brightness setting you have it set at. Then, after sensing zero movement, it turns off after 225 seconds, or just under 4 minutes. The Omega does have a twist to this auto on/off. If you leave the Omega sitting for 12 hours, it will turn off completely to save battery life. I have a love/hate relationship with this. Since I use it on a 22 rimfire rifle, this feature is great. But if you want this optic for a bedside firearm, the auto on might not work when you need it. Mainly because the gun will probably not get moved enough to keep the auto on/off working. For duty use, it is probably fine because the movement of it being on you will keep the sight from turning off. Something to think about. Gideon does have other optics without the 12 hour off feature, so one can always check those options out.

  Another feature I like on the Omega is the top load battery. With the top load battery, you will not have to take the sight off to change it. Gideon gave the Omega a CR1632 battery. They spec the battery life at “up to 50,000 hours”. So if you leave it on the brightest setting, I do not know how long the battery will last. But I really do not think anyone has to really worry about the battery life.

  The Omega is super light. Gideon states that it weighs 1.8 ounces with the battery. This is one of the reasons I decided to mount it on that lightweight 10/22. As far as physical size, it is 2.06 inches long x 1.21 inches wide x 1.25 inches tall. So even though it has a good window size, the Omega is still small. 

  Sighting in the Gideon Omega was super easy. It was almost centered up after mounting. I even sighted it in right before a local steel challenge competition. I set a target about 15 yards away and went to town. Adjustments on the Omega have actual clicks. Yes, they are tiny sounds and feel, but at least it has them. I am a fan of clicks on these micro optics. If it does not have them, how do I know how far I actually moved the adjustment screw? Thank you Gideon for putting actual clicks in the adjustments.

  I was really happy with how the Gideon Omega works. I know it will handle the recoil of a pistol, at least based on my previous experiences with other Gideon Optics. I was surprised at how well I liked the Omega on a small rifle. It performed fantastic. Yeah, I am not a fan of the 12 hour auto off function, but since I have it on a competition 22, it does not really matter. Would I recommend it to someone? Yes, it is a fantastic green dot reflex optic. 

  Sometimes life throws you a curveball and you hit it out of the park. I had not planned on mounting the Gideon Omega to a 22, but I did. The Omega works so well on that 22 that I am not taking it off to install it on a pistol. The green dot is clear and a great size. Gideon is really the one that hit the home run with the Omega. I love the size and features it has. If you want to check it out, head over to Gideon Optics.

The Gideon Omega does exactly what it needs to. It provides a big window, competition style optic that performs. Shake-awake type functionality is welcome and is essentially the only "advanced" feature an optic like this really needs. I also appreciate the easier to actuate buttons versus some other brands. This is a tradeoff of course as you could get some accidental presses in some situations, but it suits my preference for fast adjustment. After my first 200 rounds with the Omega I've noticed zero issues and will be running this solution for competitions going forwards (and saving hundreds in the process).

Viridian RFX45

  The enclosed emitter, red dot sight market, is getting packed with options. One of those options is the Viridian RFX45. Because it is from Viridian, it uses a green dot, not red, as green is what Viridian is known for. The RFX45 is mainly designed for pistols, but can be used on rifles. I’m mainly going to focus on it as a pistol optic.

  As mentioned, the RFX45 is a closed emitter dot style sight. Some people have nicknamed them “mailbox” sights, since they look like a mailbox sitting on top of your pistol. This is due to the square, boxy shape of the sight. The closed emitter sight has some distinct advantages over the open emitter style. For instance, the RFX45’s emitter won’t get dust or moisture on it. So the image of the dot stays clear. Yes, dust and moisture can get on the outside lenses, but this doesn’t affect the emitter itself and is easily cleaned off. I find enclosed style dot sights are easier for me to find the dot. This is due to it being easier to look down a tube, since my eyes find the center of a tube naturally. I know the RFX45 is technically a rectangle, but it still works better for me. To me there are only two disadvantages, and they really are small ones. Enclosed style sights, like the RFX45, can weigh more than open emitter style. The RFX45 only weighs around ¾ oz more than most open reflex sights. The RFX45 is still light enough that, most likely, you won’t have to change recoil springs, I didn’t. The next disadvantage could be their size. You might be more likely to hit it on something. Or, it might be harder to conceal under a shirt. Other than that, mailbox style sights, like the RFX45, are a great sight option.

  Most of the closed emitter sights you encounter will have the ACRO footprint, the Viridian RFX45 is no different. The ACRO style footprint is a little unique, in that it is kind of like a mini picatinny rail. This means that you will need an adapter if your slide is not specifically cut for an ACRO.  Do not fear, Viridian has different options as to what adapter plate the RFX45 comes with. Either a MOS, RMR, DOCTOR, or a low or high mount. The high mount is to mount it on an AR style rifle. The RFX45 I was sent had the MOS adaptor as the RMR ones were not out yet. I used a Primary Machine plate and it worked just fine. I do like how Viridian uses an “Industry Standard'' mounting platform for the RFX45.

Bottom dot is from the fiber optic front sight.

  The Viridian RFX45 is packed with useful features. First, the RFX45 has Instant-On. So whenever the sight senses motion, it turns the green dot on. If it sits for 2 minutes, the dot goes off until it senses movement again. This feature worked flawlessly in the RFX45. I had zero problems with it. Next up is the 50,000 hr battery life. This long battery life is also attributed to the Instant-On capability and its CR2032 battery. The green dot size is listed as 5 MOA which is slightly larger than some others. Since this is a green dot, the 5 MOA dot appeared to be slightly smaller to me. But either way, the 5 MOA dot size worked fine for everything I did with it. The RFX45 has 10 brightness settings, 2 of which are night vision compatible. At the highest setting, the RFX45 can be seen in direct bright sunlight. During my shooting experiences, some in bright sunlight, I could see the green dot just fine. 

  Window size can play an important role when choosing an enclosed red dot/green dot sight. The Viridian RFX45 has a 24mm wide x 15.5mm tall window size. This window size is wider than most of its competition. Most are 15mmx15mm. As mentioned previously, this window size makes the sight super easy for me to pick up. This includes under recoil, the draw stroke, and transitioning between target to target. The clear green dot probably helps a little with that too. All I can say is that I pick up the RFX45’s dot faster than my open reflex sights.

  Being the RFX45 is one of those mailbox style sights, I better explain some about its style. Yes, it’s square. But more on point is that the battery is housed at the top of the optic. So no removing the sight to change the battery. On the left side is a rubber pad with the up/down brightness buttons. The glass has an ever so slight tint to it. I never even noticed the tint, even on darker days. It’s super clear. Speaking of clear, the dot is extremely clear also. I have an astigmatism, and the dot doesn’t star out as much as some of my other green dots. For those of you with normal eyes, you will get a super clear round dot. I mounted the RFX45 to a Grey Ghost Precision slide that was cut for an RMR. Even with an adapter plate, the RFX45 sits level with the top of my slide. This allows me to still use the tall iron sights that are on the pistol. 

  So, if you are in the market for a “mailbox” style sight, do take a look into the Viridian RFX45. It may cost a little bit more than some others, but you are getting a quality enclosed green dot sight. I used it quite a bit and it never failed me, something I can’t say about the ammo I was using. You get a lot of high end features in the RFX45. You can check it out at Viridianweapontech.com

Viridian RFX 35

  Viridian Weapon Tech recently came out with a few pistol mounted green dots. Keeping in Viridian fashion, they only do green, hence the green dot and not a red. All of their green dots have the same features, they just are different sizes with different mounting footprints. They sent out the RFX 35 for me to try out, It uses the RMR footprint and has a huge viewing window.

  In the current pistol mounted dot sight market, there are a bunch of important features the sights should have. The RFX 35 has most of these. First, it has an industry standard footprint, a RMR in the 35’s case. Next, I feel it should have some auto on feature. Viridian’s RFX 35 checks this box as it has their “instant-on” technology. What this does for you is turn the green dot on, when any slight movement is detected. The RFX 35 turns off and into this mode after approximately 2 minutes of being stationary. The last option I think these small dot sights should have, is night vision compatibility. I don’t use this feature, but I feel it is worth having. The RFX’s lowest 2 settings are NV compatible. 

  One of my favorite things about the RFX 35 green dot is its window size. The viewing window is quite large, measuring in at 22x26 mm. This is essentially a 1 mm shorter, and 1 mm wider than its commonly known competitor, the SRO. The window is also very rounded in shape, with a flat spot near the bottom. This means that no matter what you are doing, the green dot in the RFX is super easy to pick up. It also makes transitioning from target to target faster since the target comes into the viewing window sooner. I found it extremely fast to use on my Sig P320.  

  As previously mentioned, the RFX 35 uses a green dot. Viridian uses a 3 MOA dot size for the RFX. I thought the dot size was very useful. Not too large to cover up close targets, but small enough to be used, when accuracy is needed, on those 50 yard targets. Most people tend to see the green dot better than a red one. For me, I get less of that “bloom” effect with green, that is due to my astigmatism. The RFX 35 uses a “+” and “-” to adjust brightness. The “+” is on the left side, and the “-” is on the right side. I like this layout as you don’t accidentally push the wrong button. There are 10 total brightness adjustments, 8 are daylight and the other 2 are NV. The green dot is easily visible in bright sunlight on the highest setting. To adjust the green dot for windage and elevation, there is a supplied allen wrench. It adjusts in 1 MOA “clicks”, except it doesn’t have clicks, just the turn screws. This doesn’t hurt the functionality, I just prefer clicks to make adjustments easier for me. 

  Another advantage to the RFX 35 is its extremely low profile. This little green dot sits lower than any of the other RMR footprints sights I own. Part of the reason it sits so low in the slide, is that it has a bottom mount battery. No side or top load battery here. I prefer to not have a bottom load battery, as I don’t like to remove things to change batteries. Is this a deal breaker? No, it’s just a slight inconvenience every couple of years when it needs to be changed. With a 30,000 hr battery life, it’s not like you have to change it all the time. 

  In the end, I am really liking the Viridian RFX 35. The green dot is crystal clear and is easily picked up with my eye. The window's viewing size is fantastic. Plus, it has that industry standard mounting footprint. The RFX 35 has been a really good sight for me. If you are looking at a large window reflex sight to mount on a handgun slide, or possibly a rifle, the Viridian RFX 35 may just be the ticket. Check it out, along with the other RFX series sights, at Veridian’s website.

Pretty nice if you get it on sale

500 rounds through my pistol with this dot and it went from being a safe toy to my EDC. I got the 35 and it turned my pistol into an entire new machine. Easier to sight in than my holosun, and over $100 less. Will be getting the 15 for my smaller pistol and ditching the holosun 507k I have on it. The green dot is super easy to see. Honestly surprised how much better I like it over my holosun.

Was honestly surprised by the dot. I expected it to be crap after seeing the glass fell out of both the reviews I watched. Ended up being a great purchase. My only gripes are the fact it has to be removed to replace the battery and that it's kind of difficult to remove the wrench used to adjust. Would be so much better if they used the same style screws as pretty much every other big-name dot to adjust. I never have an allen wrench on me, but I always have some kind of small device that can be used as a flat head.

Swampfox Liberty green dot

  Swampfox has been making a name for themselves over the last few years. Over these years, they have been greatly improving their optics lineup. One of these is the Liberty green dot, an open reflex mini-sized dot sight. The Liberty is a welcomed improvement over their previous mini red dot. It is essentially a new streamlined, updated, and improved version.

  The Liberty covers all the normal bases when you think of a mini red dot, or green in this case. It’s small (size below under FNBs). It uses a RMR mounting footprint. The RMR footprint is what I think should be a standard. Because of this footprint, many aftermarket companies make pre-cut slides for most of the popular pistols out there. Making it an easy process to get the sight mounted up and in use. It also gives various mounting options for if you were to use it on a rifle. The Liberty is made from 7075-T6 aluminum, and then anodized. Pretty typical in today's market. Of course it has no magnification, or 1x, and is parallax free. The window size is 16x22mm, which works well for something like a carry pistol. 

  Besides all the “normal” mini dot stuff, the Liberty has some useful upgrades. First off, it is a green dot. Yes, you can also get red if you like, but this one is green. The dot is 3 moa, a really good size for a pistol. It has 10 brightness settings, all accessed by 2 recessed buttons, on the left side of the sight. Swampfox also put a CR1632 battery in a top mount, so no pulling the sight off to change the battery. 

  Auto on/off is one of the best improvements Swampfox made to the Liberty. They call this “Shake ‘N Wake”. What the Shake ‘n Wake does is automatically turn the sight on and off. After around 4 minutes of non use, the sight goes into a power save mode. To power up the green dot again, just move the sight. The movement it takes is very minimal. Just tapping on it with your finger will wake the sight up. It also wakes up on the last brightness setting that you had it set on. So if the Liberty is on the highest setting, it wakes up there, and so on. If you really want to turn the Liberty completely off, you can hold the brightness down button for 3 seconds to turn it off. Then you must touch the brightness up button, to turn it back on and into the Shake ‘N Wake mode. I personally really like this function. The sight is ready to go when I need it. It has always displayed the green dot when I pick up the pistol it is mounted on. Battery life is stated at 4000 hrs on the medium setting. Since it has the Shake ‘N Wake function, the battery actually lasts longer than you would think. Swampfox says to change the battery about once a year. I don’t know if I’d go that long. Maybe every 6 months. The batteries are super cheap anyhow. I have had the original battery in it for 3 months without any problems. I also leave it on the second to the highest brightness setting.

  Sometimes sights, like the Liberty, can be prone to accidental droppings. This doesn’t always seem to do anything to the sight, but sometimes it can. So Swampfox came up with their “Ironsides” protection shield. The shield is made from 304 stainless steel. 304 stainless is pretty darn strong from my experience. The Ironsides literally wraps itself around the Liberty. It leaves a tiny space around the optic to help keep the Liberty from the abuse of drops and other impacts. It does this without really adding much size to the total package. Thankfully I haven’t dropped it yet, but I do feel protected if I do. 

  Since Swampfox knew that I might mount the LIberty on a number of different pistols, they included their “ultimate red dot screw pack”. The screw pack contains a plethora of red dot mounting screws. Both different thread pitches, and lengths. They also include a few extra long screws for “custom mounting”. Of course I had to cut a couple of the extra long screws down to get the Liberty and Ironsides to mount up on the Strike Industries slide. But that’s what the longer screws were for. The screw pack is a nice thing to have around, especially if you mount up a lot of these size sights.

Dot reflection can be seen right on top of front sight. Dot in center is actual dot and very clear.

  Now, you probably are wondering what my thoughts are on the green dotted Liberty. It works well. The green seems a little nicer to the eye, not as harsh as red. I can still pick up the dot easily. There is a small reflection of the dot in the bottom of the viewing window. This is a little annoying. The reflection is not near as bright, so it's not like you can mistake it for the dot. I really like the Shake ‘N Wake feature. The green dot is bright enough to be seen in direct sunlight, a good thing. The window is super clear, without any real noticeable tint. The Ironsides shield is great, I’d definitely say it’s worth the extra money. The Liberty also uses a RMR mounting footprint, so there are plenty of mounting options available for it. I’d say the Liberty is a good little mini green dot sight.

  Swampfox has done some good stuff with the Liberty. The Liberty is leaps and bounds better than Swampfox’s first mini red dot. Between the Ironsides protection and green dot availability, you have plenty of options to choose from. Go check out the complete line of Swampfox optics over at their website.

So far, so good. Basically a budget DPP on the RMR footprint. Very solid idea. Lots of great features here. Bang for your buck this is hard to beat. Durability has been great so far, I have one riding 45° on a rifle and one on a Glock 21 (.45) that I had the slide cut for. They have been holding up fine. My faith in them grows the more I use them. My only complaint is that the windage and elevation adjustments do not have clicks. This may or may not bug you, but it bugs me. Also a shield for the justice would be cool, it would really hammer home the budget Delta Point pro angle.
