Velocity Adjustable Gas Block

Chad Wallace

Velocity Precision is known mainly for their triggers. They have introduced some other items lately, One of those is an adjustable gas block for AR15 rifles. If you are looking to tune a suppressed rifle, or just want less strain on your rifle’s parts, an adjustable gas block just might be what you need.

An adjustable gas block can be very useful. By allowing the gas system to be adjusted, one can “tune” the rifle. If you run a low mass bolt carrier group (BCG), adjusting the gas down, will smoothen out the recoil impulse, and not beat the crap out of your equipment. Suppressors are notorious for “over” gassing the recoil system. So tuning the gas block, when running suppressed, is also a big plus. Another advantage to an adjustable gas block is being able to tune your rifle or pistol for the specific ammunition you use. As you can see, there are numerous reasons why someone might want an adjustable gas block.

The Velocity adjustable gas block has many features. It is of the “low profile” design, manufactured from stainless steel, and then black nitride coated. So it should last a lifetime. Velocity also cuts some diamond shapes in the gas block to help lighten it up. The gas block has a 0.750” journal diameter, which is pretty much the industry standard. Though I would like to see a 0.625” one for lightweight builds. The Velocity gas block uses 2 set screws on the bottom to clamp it down tight. Also included is a new gas tube roll pin, which was nice. Since the one that came with the gas tube went flying across my garage. It also comes with the allen wrenches to adjust it.

Adjustment on the gas block is pretty straight forward. On the front of the gas block, is a brass set screw. The brass screw is used as a lock screw, to keep your adjustment from wandering. Loosen it first before making any adjustment on the adjustment screw. The gas adjustment screw is stainless steel, and located on the left side of the gas block. To adjust the gas flow, turn the SS screw clockwise to decrease the amount of gas being sent to the BCG, and turn it counter clockwise to increase the amount of gas to the BCG. Once you have it adjusted where you want it, tighten the brass screw back down. The SS adjustment screw just blocks off flow by making the gas hole smaller, simple as that. If you are switching between suppressed and un-suppressed, the gas block can get annoying to keep adjusting. But, Velocity coats both screws in hi-temp anti-seize for a lifetime of easy adjustability.

I installed the Velocity adjustable gas block on a 7.5” AR pistol build. In my opinion, the shorter the barrel, the harsher the gas system is on the BCG. The barrel I used was not dimpled for a set screw style gas block. So I just lined up the Velocity gas block, and tightened those set screws down. The gas block hasn’t loosened up, or moved, on me yet. I did use some medium strength thread locker on the screws. I opened up the adjustment screw, all the way, at first. The pistol ran fine on an assortment of ammunition. I then proceeded to adjust it in, 1 turn at a time, until it started malfunctioning with the lightest loads that I regularly shoot. Then I backed it out ½ turn and locked it down with the brass screw. I get a much softer recoil impulse now that the gas system is adjusted for the AR pistol. It really did make for a much nicer shooting pistol. The only problem I ran into, was that the allen wrench provided was to short to tighten the lock screw, at least with my chosen handguard. This is not a Velocity Precision problem, it’s a handguard problem. So check your handguard to see if it blocks the adjustment screw.

The Velocity adjustable gas block can be useful. If you need some gas system adjustment, but won’t be adjusting it a lot, this might be exactly what you are looking for. The gas block is well made, fairly light, and won’t break the bank. Go take a look at Velocity Precision, gas blocks aren’t the only thing they make!

Velocity Pistol Caliber Carbine (PCC) Trigger

Review, Velocity Triggers, Trigger, PCC

Velocity Triggers has come out with a new trigger in their MPC (Marksman Performance Choice) line. This particular trigger is for pistol caliber carbines (PCC) that use AR15 trigger assemblies. I am a big fan of the original MPC trigger. I have also become a fan of the PCC trigger. They informed me at SHOT 2019 about the new trigger, so I requested one for review.

The PCC trigger has the same features of the original MPC line. Probably the most notable is the ⅜” wide trigger shoe. Besides being wider than the average trigger shoe, it is available in a wide assortment of shapes and colors. This time I asked for a green flat, grooved, with finger stop shoe. I also have a curved radiused and flat radiused that can be swapped on in place of the original shoe. Yes, different shoes are available and can be installed on the trigger assembly. No more being stuck with a single shoe design. Additional shoes can be purchased individually. The shoe attaches with an allen screw. One big advantage to this attachment style is that the shoe can also be pivoted. I have mine pivoted just slightly so that the pad of my finger sits flat on the shoe.

Since a PCC functions differently than a standard AR, Velocity designed the trigger differently. The most notable difference is how the hammer is designed. It has a definite curved shape to it with more material. The disconnector is also slightly different. When laid out next to one another, it is easy to see the differences. Standard AR triggers don’t always work in the PCC”s. This is because the bolt has so much more mass. The mass can cause a standard trigger to bounce off the disconnector and cause a double fire. I’ve had this happen with non-pcc triggers. The Velocity PCC trigger does not have this problem. It has ran flawlessly for me.

Standard trigger on left, PCC trigger on right

Velocity triggers’ have great trigger pulls, and the PCC is no exception. The PCC trigger has a pull weight of 4lbs and is non adjustable. When I measured it, it was an average of 4lbs, so it is consistent. As with all their triggers, it has zero creep, a smooth break, and positive reset. Along with that, there is also very little overtravel. Part of the reason the trigger has such a nice feel is that they Nickel Teflon coat the internal parts. This nickel teflon provides a superior resistance to wear, corrosion and friction. So to say it again, the PCC trigger has an excellent trigger pull. The trigger will also work with standard caliber AR’s.

As an added bonus, Velocity sent some extras also. They sent a 3-hole Sentinel trigger guard in green. The Sentinel is made from aluminum and has more room for gloved hands. Also in the package was one of their new “Wicked” extended magazine releases. It looks like a face with straight teeth. When you see it, you’ll get the idea.

I used the PCC trigger in a standard AR lower. This lower usually runs a Stern Defense Glock mag adaptor, but I also used an ENDOMAG. The trigger functioned great with either system. I had zero failures to fire and zero double fires. I would say that’s a win. Purposeful double and triple shots were very well controlled also.

This PCC trigger is impressive! It did everything I wanted it to. If you are looking for a PCC trigger, or any other AR drop in trigger, go give Velocity Triggers a look. They keep impressing me with their products

Velocity Triggers, Review

Velocity Triggers MPC (Marksman Performance Choice) Trigger

Velocity Triggers, Review

I have been trying to get my hands on a Velocity trigger for some time now. It finally happened when they sent me their new MPC (Marksman Performance Choice) trigger. Velocity Triggers has been making cartridge style triggers, for the AR platform rifles, for awhile now. They are based out of Phoenix, AZ and their triggers are 100% made in the USA.

The MPC trigger installs much like any other AR cartridge style trigger. With the exception of the trigger shoe. First remove the old trigger parts. Which includes removing the pistol grip and taking out the safety. Now you can drop in the MPC without the trigger shoe on it. Yes, I said it, without the trigger shoe. As one big feature of the MPC is the changeable shoes. Install the trigger pins, tighten up the two side screw on the trigger cartridge with the supplied allen wrench. This puts pressure on the trigger pins and keeps them from wandering out. Now that the trigger is in, Take the other supplied allen wrench and install the trigger shoe to the little nub sticking through where a standard trigger would be. The new trigger shoe has a little bit of twist built into it. What this does is make the MPC shoe pivot slightly left to right on the trigger shaft. This way it can be set for personal preference and then tightened down. One can install the shoe with the trigger guard on, but I found it easier to remove, or pivot the trigger guard out of the way. Once the safety and grip are reinstalled, check the trigger for proper function.

The straight smooth with finger stop, is the trigger I received. The finger stop is just a little hook, on the bottom of the flat trigger, that helps keep your finger from sliding down and rubbing on the trigger guard. Velocity Triggers has multiple options for trigger shoes and colors. The smooth triggers are also radiused across the shoe, from left to right. This makes for a very comfortable feel. If you don’t like smooth with a radius, they offer a serrated (grooved trigger) also. I felt the serrated ones, and the are nice also, just not my cup of tea, I do know people who like the serrated over the smooth. Now along with the textures, you can also get curved or straight (without a finger stop). Oh, and all are available in a number of colors. One really nice feature of the MPC, is the availability to buy extra trigger shoes for a whopping $14.95 each. All of the options, as well as the purchased trigger, use a ⅜” wide trigger pad. This is a little wider than a stock trigger and much nicer.

Now that I’ve bored you with everything, I’ll get into how it feels. Velocity has two different pull weight options, a 3 or 4 lb pull. I received the 3 lb one. It measures right at 3 lb’s on my trigger scale, and does it consistently! I thought 3 lbs was going to feel heavy, but that is not what I found with the MPC. It has nearly zero takeup. I can’t even see any, yet alone feel any. So when shooting, one just applies pressure and the trigger just fires. The break on this MPC is fantastic and super crisp. There is a slight bit of over travel, yes slight, but hardly noticeable. Then there is the reset, strong and very tactile. I really liked the crisp reset. Some other triggers I’ve used can be somewhat mushy, this is definitely not the case here. The MPC is a single stage trigger, if you hadn’t figured that out yet. Because the MPC uses a different style of trigger shoe, the trigger reach is longer. I liked the longer reach as it placed my finger more on the pad, and less on the knuckle. If you have a really short trigger reach (think children) it may not be the best option. If you are looking for a super fast trigger, the MPC might just be it.

I have shot lots of rounds through this trigger. Even used it with my .22lr conversion. It has enough hammer energy to have reliably fired the .22lr rounds and anything else I ran through it, including steel case 5.56. The MPC feels exactly the same as it did new. I mention this because some other triggers I have used felt better after using them for awhile. I attribute the “feel” to the hammer and disconnector being plated in NP3. NP3, by Robar, is a Nickel Teflon coating that creates low friction and high wear resistance. Either way, it performs well.

If you are looking for a new trigger for your AR style rifle, look into the Velocity MPC. I was really surprised at how well I like this trigger. Plus the added benefits of a longer reach and wider shoe make it feel much better than your standard trigger. Even though the price is a little higher than I would like, I think it is acceptable for the quality and options the MPC has. If you are in the market for an AR trigger, the MPC from Velocity Triggers might be the ticket.
