Maxim cqb pdw gen 6 brace - Maxim Defense Industries CQB Pistol PDW Gen 6 Brace for AR15, Small Buffer/Spring

This brace completed my 45 acp build, this gets very small, much smaller than the models I have that have a longer length buffer tube. Ran great through 400 plus rounds using their buffer and spring with a side charge bear creek 45 upper. Their are multiple models but this comes with the buffer needed for PC builds, worked good on 45 and sure it would for 9mm/40 builds
