Questions & Answers
Will this buffer tube work with a 9mm conversion? And what braces fit on it?

This tube will work on 9mm AR pistol builds. Per the manufacturer’s website, “This model of the Hex Tube lineup is not designed to accept a Pistol Brace.” The manufacturer also offers a Hex-2 version that is round at the back that will accept non-adjustable SB braces that fit on a 1.2” tube.
