    Completed my Build

    Wanted an ar pistol in 300 blk. Put this and a 9” BCM upper on a lower I built myself and once I changed out an H2 buffer for an H buffer it shoots perfectly. BCM is my goto for parts because they put out an exceptional product.

    Pistol Buffer Tube

    Top Tier, as expected. Building, excuse me, assembling, my first AR pistol, and I thought this is what I needed for a pistol brace attachment. Found out later that (1) the brace I bought came with a mil-spec carbine tube; and (2) I needed a standard carbine buffer tube, not a pistol tube. HOWEVER, given the uncertainty currently faced with the ATF’s “Honey Badger Q”-reclassifying-definitions-and-function-for-a-once-again, I’m glad I have it, just in case.

    AR Pistol arm brace fitment

    BCM PISTOL receiver extension gives tight, friction-fit for Sig Brace SOB. It's a must have for the new Sig brace line which require a slightly larger diameter receiver extension than previous generation products. Heavy duty BCM-awesome as usual.

    Exactly what I needed

    Works as advertised. Needed a pistol tube that fits a Gear Head Works Tailhook Mod1 pistol brace, and this is the right diameter. Good finish on the tube, and reasonably priced.

    Better than the generico

    Swapped out my no-name pistol buffer tube for this one when I was encountering problems trying to fit a Thordsten cheek rest. The cheek rest slides right onto this one and once installed stays in place. On my previous tube it would continue to slide around (which sometimes caused it to interfere with charging handle operation due to an unnecessary taper in the tube). With the BCM tube, it locks on and stays in place. Also its 3/4" longer which relieved just enough spring tension for my bolt to lock open on an empty mag, whereas the previous tube was not allowing that (running 300 blackout 9.5" barrel supersonics). Overall, I'm a lot happier with my gun now that shit isn't sliding around and I can keep my cheek rest where I need it.
