Black Rifle Tactical Gas Tubes

[Eurodriver]

Howdy,

I run suppressed on a few rifles exclusively. Some have Gemtech SBCs some dont. Some have mini cans some have full size cans. Some are 16” some are 10.5”. I always shoot quality 5.56 but sometimes Wolf Gold (even though it is horribly inconsistent - https://www.m4carbine.net/showthread...h-testing-pics )

BRT has a million choices which to select. Barrel length, bolt carrier, ammo used, etc.

How reliable is BRT in selecting the correct gas tube size for reliable use (but also effective at reducing over gassing)?

The preset tubes are available for the most popular configurations.

On the configurable tubes, we get sizing correct on the first try better than 95% of the time.

When an adjustment is required, it is almost always due to some weird components being used.

Pappabear had at least 2 spec'd by BRT, and they were spot on. The tubes are very effective.

Just give him as much specifics and what you want. He should nail. I told him I’m going to run 100% and my gun almost has enough umph to cycle but not consistent. Which is what I wanted. I didn’t want to sacrifice reliability because I run shit dirty and dry way too often.

Mine where for LMT MWS guns which are gassed so the would run any countries shit dirty crappy surplus ammo, (is my guess) military grade weapons.

Thanks for the info guys. I’m always interested in ways to reduce gas that don’t involve set screws and moving parts.

I'm running two as well Euro, no complaints.
The one on an 11.5" BCM barrel made a significant improvement.

Are these to stop/help reduce gas to the face? If so, I'm going to need 2!

What sort of improvement did it make? I'm always looking to learn, and I haven't done any work with these.

I’m running the preset one for suppressor only use, on my 10.3” DD barrel. (.070” gas port.) There is virtually no gas to my face anymore, I shoot left handed too, and less recoil. It was the best upgrade I’ve ever done to a rifle.

I have several BRT barrels and gas tubes. All have been perfect. The guns shot so smoothly that they feel like they are running too slow but I’ve run them all super hard and have had zero malfunctions. It took a little bit to trust How Clint works his magic but he’s got this locked.
I don’t see a reason to build another rifle without a BRT barrel.
