A lot of people are switching to a red dot optic on their handgun. Because of this, they most likely will need a set of back up iron sights that can be seen through the optic. This is where Angry Bear Arms comes in. They make inexpensive sights for Glock and M&P pistols in various sizes from short to extra-tall. The tall RMR set was the one sent to me for review.

Angry Bear Arms has quite a few options when it comes to sights. All are made from US sourced steel and made in the USA. The sights have a black nitride coating, so they should last a very long time. What makes the sights stand out, is the $40 starting price for a set. The option I chose for review was the - Glock RMR Cut, Tall profile, Fiber Optic Serrated Sight Kit. Price on it is $45.95 and is from their “Bear Bones” line. This line only comes with the front and rear sight, front sight screw, rear sight set screw, and the red and green fiber pipes. Other kits they make come with a sight tool and/or various front sights of different heights. Those are more geared for someone who wants to get a precise impact point with their chosen ammunition.

The RMR tall kit is basically for use as a low witness back up for the red dot sight. The sight notch base just barely sits above a recessed mounted red dot. Hence the RMR in the name. I am using a Holosun 507C with them, and it works great. The Holosun is recessed into the slide, and must be for these sights to work. Angry Bear does make a MOS extra tall sight for red dots that are not recessed.

Installation is pretty routine. Take out the old sights, install Angry Bear Arms sights. Since these are Glock sights. The rear sight is dovetailed in, so a sight pusher, or some other way of sliding the sight into place, is needed. Angry Bear also has a set screw, that screw down from the top of the sight, to help hold it in place. The sight hasn’t moved on me, or do I think it ever will. The front sight is screwed in from below. I used blue (242) loctite on the screw to help keep it from backing out. As with all Glock style front sights, don’t over torque the screw. Since the front sight is fiber optic, now one must install the fiber rod into the sight. I chose green, they supply red also. Green was chosen because it is not the same color as the red dot optic. Take a lighter, or something hot, and heat the end of the fiber up. Then just press on it a little to swell it out. Slide the rod through the front sight, from back to front. The fiber should stop when it hits the swollen part. Then cut the other end off, leaving a little bit of room to heat it up. Then, when hot, press the end to swell it and hold the fiber in. Angry Bear Arms supplies enough fiber for you to mess up a few times. Now you can go shoot the handgun.

These sights have pretty much everything I want in a sight. The rear notch is just wide enough to allow the right amount of light on each side of the front post. I really do like the sight picture. Yet the front sight is narrow enough to give good accuracy. I opted for the serrated set, which puts some nice horizontal lines on the face of the front and rear sight. This helps cut down on glare, either from the sun or a flashlight. Yes, it really does cut down the glare over smooth sights. The rear sight has been smoothed out on every corner of it. This is a nice touch for the price and it will keep it from wearing on your clothes. The front side of the rear sight is straight and flat. This would give you a good purchase to rack the slide off of something like a table, etc. This would only work if there wasn’t a red dot in front of it. The front sight is nice and square, giving a really good sight picture. One can’t really dehorn a front sight like you can the rear. I definitely would use these RMR tall sights without an optic. They are a nearly perfect sight picture for my taste.

If you're in the market for a quality, inexpensive sight set, go check out the Angry Bear Arms sights. I could not be happier with the form and function of the set I received. Next time I get a new slide, I definitely know where I’m headed to get some sights.

Swampfox Optics is a new optics manufacturer. They seem to be doing some good things, like the Kingslayer. The Kingslayer is a micro red dot. When I first heard about these, I ask for a review one. They shipped one right out and here we are.

The Kingslayer micro red dot is your typical reflex sight. It mounts using the industry standard RMR footprint. A huge plus when mounting it on a pistol slide. It also comes with a picatinny mount. As one can expect, it is fairly small at 1”w x 1”h x 1.8”l. The size gives it a 22mm window to look through. I found the 3 MOA dot to be very useful. Not too small, but not too large, kind of in the easy to pick up and see category. Weighing in at 1 ounce, it is very light.

Function of the Kingslayer is pretty self explanatory. There is an up and down arrow button on the side. This increases and decreases the brightness. The up arrow also turns the sight on when pushed. The down arrow will turn the sight of after holding it down for about 3-5 seconds. Also the Kingslayer has an auto off after 4 hours of button inactivity. Now comes one of the deal breakers for me, the battery life. The kingslayer uses a CR1632 battery. It’s smaller than your normal CR2032. Battery life is stated at 200 hrs on the high setting, and 3000 hrs on the lowest. The one saving grace to the battery life is the fact that the battery tray is on the side of the unit. No taking it off to change the battery.

After receiving the Kingslayer, I mounted up on my Grey Ghost slide. Partly because it has an RMR cut-out. No problems with mounting. I then zeroed it. It has tiny screws for windage and elevation. The screws are snug and take a little bit of force to turn. A good thing since they are not “click” adjustable. Then I preceded to……..break it. While moving stuff around on a tall bench, the pistol fell onto concrete, on the Kingslayer. The fall was from 4 feet. The glass in the Kingslayer cracked, ugh! I could still see the dot, and it held zero, so I shot it a little bit. When I contacted Swampfox, they immediately sent me a call tag and replaced it with a new one. I’ve been a little more careful with this one.

Besides my self induced problems, the Kingslayer has worked well. It’s held zero, even after taking it off and installing it on a different slide, and then back. The side battery tray is a nice feature. The 3 MOA dot is easily picked up, but not as well as some . I attribute this to the 22mm window size. It is noticeably smaller than some of the other micro red dots I’ve used. It could just be the shape. For a fairly reasonable priced micro red dot, it seems to perform as advertised.

If your in the market for a slide mounted red dot, the Kingslayer might just be the ticket. At around $200, it is a good way to try out using a slide mounted red dot. If you then decide to upgrade to a “name”, you can put it on something else with the picatinny mount. Go check out Swampfox Optics, they seem to be doing some decent stuff.

Ok sooo a long story... I bought a Kingslayer off of eBay from an armed forces officer that had bought two. I’m a special operations officer and deal with very expensive equipment. The good: the product is solid, crystal clear glass and great concise dot.

The bad: the thing drained batteries like nobody’s business even in the off position.

The amazing: I contacted Swampfox via email even though I didn’t purchase it from them. In a matter of minutes I was contacted back and advised that they would honor their warranty and would ship a replacement and mailing slip right out. I received it only to find it had the same issue. Once again I contacted Swampfox and again I was immediately contacted back. This time they were not so fast to just send a replacement, Robert and Chris worked with me hand and hand for days trying to find the glitch. At no time in this process was I ever degraded, ignored or told it was operator error. We never could quite figure out the issue so I kinda just called it a wash for buying something second hand. About a month after our last conversation I was contacted by Robert and Chris who stated that they had found a virus in the tiny circuit board and had fixed all the issues and that they were sending me a brand new redesigned model and a postage paid slip for my return as well as everyone that owned a Kingslayer! This was a long process and my optics have to work every single time they are asked to or they cannot be used due to what I do. I have waited -on purpose - to write this review so that I can state with confidence that the optic is reliable. The Kingslayer is amazing crystal clear glass that rivals optics I run that cost HUNDREDS more. I have run the optic on a pistol, ar, and mp5 with zero malfunctions. But more impressive than the optic is the company. The team at Swampfox could have easily denied my claim due to me purchasing second hand and that is even stated in the fine print of their warranty. Swampfox never batted an eye at my claims, never tried to cover up a problem and never tried to sidestep my communication. The optic I received is still on the original battery, has been used extensively and has held zero on whatever I mounted it on. For the price I believe this is one of the best red dots on the market and the company service is second to none.
