    Great option for the Vltor buffer tube

    I am glad BCM came with their version of the A5 tube. This is hard to find and the A5 system is a great upgrade to any AR15

    Homegrown A5

    A locally made, in-stock A5 option with a great finish and solid fit. Incredibly fast shipping and plenty of swag, too. How can you go wrong? I like to support my local shops and will be back for more.

    Great product

    What can I say, it's BCM and a A5 tube. I run it on 2 rifles now. A cmmg rdb 9mm with blitzkrieg buffer and a standard build with vltor buffer. Gives you more LOP and helps with recoil. Good stuff

    well made.

    Seems very sturdy, has some kind of coating inside. Intermediate buffer system runs super smooth.

    Buffer tube

    Seems like a buffer tube. I remain suspicious. If I ever manage to get enough parts together to actually make a gun, I’ll let you know. Maybe 6 months from now. Fuckin 2020.

    BCM A5 Tube

    Awsome substitution for the vltor, have purchased two of them and will continue purchasing them on my future builds. The quality is unmatched.

    Intermediate Reciver extension tube

    Great, works great. An upgrade that actually works and helps reliability. Using on a 12.5 in 5.56 solgw barrel on an aero upper, bought a second one for my 10.5in 300blk I'm using for hunting.
