BRT EZTUNE Gas Tubes

[Clint]

More great feedback with an interesting Dedicated Suppressed LMT application.

Hi BRT Team,


Five stars! It’s made shooting this gun a much better experience.

The tube BRT selected for my application is perfect.

3:00 ejection with suppressor attached. Will not pick up the next round w/o the suppressor as expected.


Specs:

16” mid barrel chopped to 12.5

Sandman S

55 grain M193

The EZTUNE Gas Tubes are the quickest, easiest way to reduce the gas drive of any barrel.

If I need to remove my gb to install a new tube, would it not be easier to just use an adjustable gb?

I think this is a nice solution for people using a FSB.

No need to remove GB. Take off rail and thread tube through upper receiver, remove GT roll pin, install new GT.

It can sometimes be a pain to install on very specific gas blocks. (Edit: undersized blocks; pain to install/remove any gas tube) I really dig BRT’s blocks because the open front allows me to tap one out with a tight-fitting punch, if necessary. But I’ve only had to do that once, because URX4. They are also among the lightest, and pinnable.

As a precaution, I always install gas tubes with a high-temp non-metallic anti-seize meant for silencers to prevent carbon bonding or whatever.

The bend in tube won't always fit through with some barrel nuts, like the Hogue one.

My experience with adjustable gas blocks brought me to the conclusion that they have no business on a fighting rifle.

They're a nice solution for anyone wanting to choke down over gassed barrels or barrels they wish to run primarily/only suppressed.

What type of adj gb, what are the issues?

True, but 95% of the time, the tube can be replaced without removing the gas block or front sight base.

The bend in tube won't always fit through with some barrel nuts, like the Hogue one.

The typical failure modes seem to be seized up adjustment mechanism, complete blow out of the adjustment guts or simple use error/mis-adjustment.

Just had one of our prototype tubes make it past 5000 rounds on a suppressed carbine.

The port is still in fairly good shape, but the tube will be retired due to a cracking on the back side related to prototype features.

The two Microtune Mk12 gas blocks you did for our 10.3s have 6k and 8k through them with no change in ejection pattern or distance. Do you really think these will have that kind of longevity on suppressed, full-auto rigs?

Also, any idea on when we can expect more Microtune kits and Mk12 SS gas blocks? I have four more overgassed 10.3s to tame.
