Bufferless AR Pistol Build: 3 UNEXPECTED Failures You Need to See
This build review highlights three unexpected failures with a bufferless AR pistol using the Brownells BRN-180S: a loose handstop, a folding brace collapsing mid-fire, and a loosening flash hider due to the jam nut system. Despite these issues, the rifle demonstrated 100% cycling reliability over 550 rounds and offers a clean-shooting piston system with excellent ergonomics, though it runs hot and has increased recoil.
