It’s a tube - Phase 5 Weapon Systems Inc AR-15 Pistol Buffer Tube

Bought this to replace a brace. The buffer tube that I received did not have the white Phase 5 logo and “PISTOL” markings, which was the main reason for the purchase. Tube has a smaller black stamped Phase 5 logo. Quality is good. Would have given it 5 stars if the markings were present and matched as advertised.
