    Products are great but I’m not ordering from any company who ignores my request to ship UPS or FedEx. USPS service is unacceptable and I refuse to use it. All kinds of companies to order quality products from.

    I pretty much agree with everyone else on here, but here I go. 7075 aluminum means this company never cuts corners, even on an item like this where a lot of other companies settle for 6061 simply because you end up putting a buttstock over it anyway...right? Wrong. I got an h2 and h3 and I've played around with different buffer tubes and this is the most solid and quiet. We the people appreciate you BCM

    Best quality in a tube!

    Posted by Adam Davidsson on Aug 24th 2020

    Bought this to replace my el cheapo UTG buffer tube (wasn’t aware UTG uses 6061 aluminum and BCM uses 7075 aluminum) and thought it was crazy that this much higher quality reciever extension came in at a much lower cost than a lesser quality one. Put alittle oil along the inside, installed my spring and buffer and now my entire rifle feels like it’s sitting on smooth ball bearings! I highly recommend BCM parts if you like building rifles like I do. Shipping was also super fast. Live on the complete opposite end of the US and I had this in my mailbox in 3 days! Can’t wait to buy more from BCM in the future!
