Its a ;

10.5 inch .82 gas port commercial off the shelf MK18 Mod 1 from Daniel Defense. Not .mil assembled.

Aero Precision Lower that looks like he Form 1 SBRed it or a factory SBR. (Model (WTBNSR10) ...Weapons Battalion Senior 10? Nice. Maybe Weapons BN bought AERO SBRs? Seems hard to believe.)

A aftermarket ambi-kit.

A vented Gemtech Bolt carrier assembly and a Gemtech threaded, not fast attach, Trek-T (Titanium) (SN 44875) Suppressor , with a PRI gas buster charging handle.

I am sure MARSOC and Marine Infantry has available to them the same MK18/M4CQBR series weapon systems that the Navy has in its arsenal for SEALs or other types that may use such a weapon in Urban and ship boarding operations.

I am going to bet the weapon in the video belongs to the CW5 as a personal weapon, as well as the Suppressor.

Glad that they are on a suppressor kick, just surprised it is an official Marine video with so many commercial names and products in it? (Lancer, Gemtech, Daniel Defense, Larue, Knights, Magpul, Trijicon... )

Based on the video, it looks like the gas system is balanced by dropping that brass at 3 o clock. However, the amount of gas blowing out that port is not something I would like. It would not help in hiding your position if needed. Likely still not a 100% solution for long term health reasons either. Seems fine for the range I suppose.


Lets talk about that gas system of this weapon.

What makes a MK18 system run amazing with a suppressor is a gas port of about half of the .82 factory size. More like .40-.42 for a suppressor. It will shoot super soft, no gas in the face, and be reliable and eject efficiently all day, everyday, for the everyday range shooter.

So why does the military just not do that? Well it took some research on my part and what I get out of it is because of our weapon requirements for different operational environments. One of the many issues why it takes us so long to adopt any small arm.

What runs and cycles in the desert must also work in the Jungle and also work in the arctic. Even under heavy abuse. Hence the incredibly large factory gas ports on contracted military DI small arms.

With smaller gas ports the weapons have less capability to perform the work from the smaller percentage of volume of the gas port to be reliable in all operational environments in combat conditions.

Adjustable gas blocks would help. But I believe the operational environment is the reason why the DoD demands a one stop solution for a suppressor with no changes to the weapon. I do not think they will get it thinking that way. IMO


All that said. I thought it was a good video proving what he set out to prove. Some more data and explanation of the parts and ammo would have been helpful.
