    BRT EZTUNE Gas Tubes

    We've got a few updates to our highly popular BRT EZTUNE Gas Tubes to share.

    But first, a quick review of what these are.

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

    They are especially handy when the muzzle device and or gas block is pinned to the barrel and removal of those items is not possible.

    The tube has the restricted gas port formed in the tube itself and is very effective as controlling gas, whether the existing barrel has an overly large gas port or is being setup for dedicated suppressed use.




    These have been out for over a year and are proven in a variety of applications.

    To further simplify selection of our EZTUNE Gas Tubes for retail sales, we've added application specific sizes that should cover most common uses.

    1) Standard MID 14" - 16" Barrel
    2) Standard CAR 14" - 16" Barrel
    3) Standard CAR 10" - 12.5" Barrel
    4) SUPPRESSED CAR 10" - 14.5" Barrel




    We've also added solutions for LMT monolithic small frame and large frame applications.



    These barrel cartridges are particularly troublesome to address with conventional solutions, as the high rise gas block is both pressed and pinned onto the barrel.

    In addition, many users run suppressors, compounding the problem.

    EZTUNE Gas Tubes solve this with a fast, effective fix for this particular application.

    Stupid question: Could this system also be a viable tool for extending the useful life of a high-mileage barrel with port erosion? For example, ten-inchers are widely reputed to need rebarreling at half the life of a 14.5 M4 IIRC, so I'm wondering if replacement tubes might be a viable crutch until it's opened up far enough to tap and mount a new port in the barrel.

    I installed a custom tune gas port on a 16" carbine with excellent results. The tubes and also having pre-configured tubes sure simplifies the process.

    Has the 14.5 -16" carbine market fallen off enough that offering an application specific tube for them isn't viable?

    I'm thinking a bunch of PSA and Ruger pistol owners should be knocking on your door...

    P.S. I'm not dissing PSA owners - the 16" carbine upper I installed the gas port on is from PSA and being overgassed was my only beef with it.

    A barrel's throat will be gone WAY before any port erosion would be an issue. I'm really interested in these tubes though. I just haven't wrenched on any guns for a while..

    For sure.

    They can drop the gas drive back down to factory.

    We'll probably add that application too.

    Lots of those out there and many are badly overgassed.

    That's good. One of these are headed your way.

    Recently ordered one of these to tame a hard bucking overgassed carbine with pinned FH. Looking forward to not running a ridiculously heavy H3 buffer anymore. If I recall the manufacturer stated they spec'ed their ports at .073 or something equally huge. I'm sure with some port erosion it is even larger than that now. Thanks for coming up with such a simple and easy solution!
