Armageddon Tactical CompTek Type 1

Armageddon Tactical’s new compensator, the CompTek Type 1, is now available. The CompTek Type 1 is designed for 5.56/.223 chambered AR-15s and is machined from 4140 steel. It has a Melonite QPQ finish for durability.

The muzzle device features a unique port layout. According to Armageddon Tactical:

Features include an internal gas expansion chamber and top ports that direct the expanding gasses upward to eliminate muzzle rise. Exit ports vent the remaining gasses to the sides and help reduce felt recoil. These exit ports are located below center to direct more gasses out the top. The design also insures there is no “dust signature” when shooting close to the ground.

Armageddon Tactical and Stealth Engineering Group SURG Submission

Armageddon Tactical and Stealth Engineering Group have released some images of their their submission to the military’s Suppressed Upper Receiver Group or SURG program. The submission makes use of Stealth Engineering Group’s suppressor technology and Armageddon Tactical’s GMS-15 Charging Handle in a special color.

I’ve not put hands on any Stealth Engineering Group products but I have spent considerable time with a GMS-15 Charging Handle and found that it does go a long way toward preventing suppressor related blowback.

Review: Armageddon Tactical GMS-15 Charging Handle

The GMS-15 Charging Handle from Armageddon Tactical is unlike any charging handle I have ever used. It has a number of impressive features but none more impressive than how Armageddon Tactical was able to engineer out any structural reliance on a roll pin or pivot. This charging handle is downright innovative.

Armageddon Tactical GMS15

Overview

The majority of the GMS-15 Charging Handle is machined from 7075 aluminum billet. The latch is machined from 4140 steel which is then heat treated. The aluminum parts are finished with MIL-A-8625F, Type III, Class 2, Teflon impregnated anodization and the steel latch is manganese phosphate finished.

The GMS-15 has two main assemblies. The first is the stem which extends into the receiver in order to pull on the bolt carrier’s gas key. This part looks mostly similar to any other charging handle except for the addition of a diagonal bore hole through the back of the stem which is part of the gas management system and the fact that it extends back slightly further than most and is visible at the back of the charging handle (it looks like a button).

The handle assembly contains the latch (and some other goodies) and the entire assembly rides forward and back on the stem. Its rearward travel is stopped by a massive, confidence inspiring lug on the stem. The handle consists of an upper and lower part that are joined by two large pillars with roll pins pressed through them. These roll pins are only used to hold the sections together. They do not take any stress from working the charging handle. The latch is secured inside this assembly and is actuated by mechanical means as the handle assembly moves back on the stem. It does not have a pivot that can be stressed by applying too much force to the latch via the typical lever that you find on most charging handles.

The previously mentioned gas management system will be of great interest to those who shoot suppressed. It consists of the previously mentioned diagonal bore hole through the stem which serves to deposit the excess gas into a reservoir in the handle. The reservoir is a large cavity with a ledge that extends slightly over the rear of the upper receiver in order to seal the charging handle opening. Most charging handles that are designed to be used with suppressor just have a ledge that redirects the gas. The GMS-15 actually closes off the top of the upper receiver’s charging handle opening.

Observations from Use

The quality of the GMS-15 is excellent. It moves smoothly in the upper receiver like a well oiled and already broken in charging handle form the moment you install it. I assume this is due to the Teflon impregnated in the finish. The parts are nicely machined and well finished. Sharp edges have been removed where possible. There is an immediate impression of quality.

The gas management system is really clever and seems to work very well. The difference in the amount of gases that always seem to be directly injected into your nose is easily noticeable when comparing the GMS-15 to a standard charging handle. It was also an improvement over the newest version of the BCM GUNFIGHTER charging handle which does have a ledge to help redirect gases but is not specifically billed for use with suppressors.

The GMS-15’s unique design makes it mostly ambidextrous. The entire handle assembly moves forward and back on the stem so, most of the time, it doesn’t matter which hand you use to pull it. The only caveat is that the GMS-15 requires tension be placed on it by the BCG, buffer, and recoil spring for it to unlock so if the bolt is locked to the rear, you will have to press the “button” (which is actually the stem extending back through the handle assembly) to release the handle.

I let 2 southpaw shooters that I know try the handle. Neither seemed to think it was a big deal to have to touch the button slightly when the bolt was locked back. Both commented that it actually felt like their thumb found the button anyway and it was really only an issue for malfunction clearance they tended to use the bolt release to release the BCG during reloads. If you are a left handed shooter, you will want to be aware of this idiosyncrasy before purchasing.

The handle assembly is probably the biggest key to why I like the GMS-15 so much. The way it moves on the stem offers several unique advantages and makes it is a joy to use. It is easy to grasp without having to be overly sharp or overly large. It is the most comfortable charging handle I have ever laid hands on.

It doesn’t twist or torque like standard charging handles when using a one handed technique to draw the charging handle back sharply. This seems to be due to how the handle moves on the stem. When the handle is drawn back, the latch unlocks, and the handle’s reward movement is halted by a large lug on the bottom of the stem. At that point, the entire charging handle moves to the rear as one unit. This seems to promote a very straight pull rather than the torqueing and twisting you may be used to with standard charging handles.

The handle design also allows the GMS-15 to operate without a large latch lever or pivot point to stress. The handle is held together with roll pins but these pins pass through large pillars which, along with the previously mentioned lug on the stem, take all the stress. The lack of hooked shaped lever means there is less likelihood of the charging handle snagging your gear.

My initial experience with an early GMS-15 was a rocky. I tried it on a handful of upper receivers and found it unlatched under recoil. I shared this with Armageddon Tactical and their response told me everything I needed to know about them as a company. I could tell it absolutely ate at Chris, the owner, that I was having a problem with his product and he contacted me several times to see how my continued testing was going.

He continued to test and diagnose problems until he found that a small number of early GMS-15s were assembled with the wrong spring and then went so far as to build a fixture to test his charging handles determine which had the incorrect spring! He was a man on a mission.

The GMS-15 that I have in hand now functions perfectly and the production issue has been corrected. Chris and Armageddon Tactical obviously have a great burden to deliver a killer product even to the point that they incur the large cost of creating the test fixture just to weed out a handful of charging handles that will probably work for most folks but aren’t exactly what he wants. That is impressive.

Wrap Up

The GMS-15 is an excellent charging handle that is easy to use. It does a great job of redirecting excess gas from shooting with a suppressor installed. It is robust and manages to remove traditional charging handle weak points through clever engineering. It is “ambidextrous” but left-handed shooters will want to read up on how it operates before taking the plunge.

From this right-handed shooter’s perspective, it is my favorite charging handle to date.

Armageddon Tactical GMS-15 Gen I Charging Handle

I have an Armageddon Tactical GMS-15 Gen I Charging Handle in hand for review and I am very impressed so far. It has a lot to offer in terms of functionality and it is fairly innovative in terms of design.

Suppressor owners will like the GMS-15 for its special gas port and chamber. The port runs up diagonally from the underside of the charging handle to redirect the excess gas into a chamber on the handle. The chamber is a large, semi-circular void that is shaped in a way it contains the gases and slips slightly over the top of the receiver to form a better seal. It’s far simpler than it sounds.

The GMS-15 is ambidextrous in that it can be operated from both sides of the AR-15. However, you should note that it’s design requires tension on the charging handle so it will not release when pulled from the ejection port side on a locked back bolt. On the first pass that sounds like a big deal but it was accounted for with the addition of a fairly large textured button (for lack of a better term) that when pressed, provides the tension necessary. This is the only time this “button” is needed and it is fairly intuitive in its use.

The most exciting thing about the GMS-15 is it’s robust construction and mechanical nature. While other charging handles attempt to overcome the shortcomings of roll pins, the GMS-15 removes them from the equation entirely (they are present but not in any sort of load bearing way). The entire handle moves back on the shaft via a robust internal mechanism. Its rearward travel is stopped, not by a roll pin, but by a large rear lug and the internal structures.

Most of the GMS-15 is machined from billet 7075 aluminum and the latch machined from heat treated 4140 steel. The aluminum components are finished with a Teflon impregnated hard anodized finish which, according to Armageddon Tactical, ” produces a durable non-reflective surface and reduces the coefficient of friction between moving parts”. The latch is Mag Phosphate finished.

I will be continuing to work with the GMS-15 to see how it holds up and how well the gas mitigation functionality works. So far, I am very impressed. The one fly in the ointment is the locked back bolt issue but a left-handed friend felt that this was overcome easily enough that he is very interested in spending more time with it.
