    Pistol Buffer Tube

    It's a buffer tube. It works like it's supposed to. The ordering and shipping were quick and easy. This is a good product it works as well as ones twice the price. I would recommend for those whom aren't into names.

    Excellent overall. It's a buffer tube... It works. Price was very good, shipping was fast, and it fit well and functions with no issues. Can't ask for more than that.

    Great price perfect fit

    Posted by LGBFJB on August 2, 2022

    Fit was absolutely prefect. Threads were cut smooth. Nice to have slot milled for end plate so there's no extra work, and can use plates I already own. Not sure what mil-spec "steel" (never heard of that) buffer other reviewers are referring too, as mil-spec is 7075 aluminum. Yes? No? If I'm wrong, I apologize, and I'll stand corrected. That being, said I didn't see anywhere that it specified if these were 7075 or 6160, maybe I can't read or I'm blind, maybe KAK should put that in the details. I bought these just for spare parts, but I did install both on 2 separate builds, 556 and 300blk, and ran them through 100rds apiece with no hiccups. Switched back to my sba3's for now. No complaints, would definitely recommend.

    Good Replacement for Rifle-Style Buffer Tube

    Posted by Baron on July 8, 2022

    This is an inexpensive way to be ready to update your AR pistol if the ATF goes ahead and publishes its new regulations on them, to use with the SB-Mini brace, the only one the ATF approves. I just wish iot could be made of steel like Mil-Spec buffer tubes, rather than aluminum.

    Great budget pistol buffer tube

    Posted by Andrew on April 14, 2022

    I didn't realize the pistol brace I got needed a round tube. This one does the bill for a reasonable amount. Held up to some initial blasting and seems to be well constructed.
