    Best price on an H3 buffer, in stock, fast shipping, a must for any AR pistol build. In pistol systems it can solve bolt bounce, lite primer strikes due to out of battery firing, ejection patterns between 12 and 3 and more....get one hell get two.

    Didn't quite fit

    Posted by Kris Flores on Dec 7th 2020

    Bought this for my 243 AR10. I should have done a bit more research but the buffer was too long and kept my charging handle from going all the way back and locking the BCG in place. This buffer assembly is about 3/4 inches longer than my original carbine buffer.

    As expected

    Heavier buffer and it does what it’s suppose to do.
    BCM customer service is most professional and prompt I’ve ever experienced compared other companies.
    Shipping department is lighting.
    Thank you all.

    H3 Buffer

    Honestly, I haven't got to shoot yet to test out their H3 Buffers but as for the company and shipping times.. they were on it. That alone is enough to make me buy from them again. Especially with all of this body covid stuff going on.. my buffer arrived quickly. I like this place so far.

    Badly needed part for my AR Build

    Posted by E.C. (Al) Maisonet on Sep 13th 2020

    The speed of processing was unreal. From the time I placed my order to the point the order was shipped and arrived at my door, was the best ever, even during the China Virus, when packages at held back from delivery by many weeks. I can only say THANK YOU for the best performance and your support for the customers out here. Looking forward to conducting more purchases in the near future.. Again Thank you!!

    Fixed my issues with my 300blk pistol build

    Posted by Kevin on Aug 3rd 2020

    I had a regular carbine buffer in my 300blk pistol build I had been making. It shot supers just fine but would fail to reliably cycle with subs. This buffer tube fixed the issue completely. It can now fire supers and subs reliably. No issues.
