Maxim Defense
Overview
The Maxim Defense CQB Gen 7 Standard Buffer Adjustable AR-15 Stock is a collapsible stock designed for AR-15 platforms. Constructed from 6061-T6 aluminum, it features a compact, adjustable design for short-barreled rifle (SBR) and pistol caliber carbine (PCC) applications. This stock integrates a proprietary buffer system, distinguishing it from standard Mil-spec or commercial buffer tube designs. GPP build data shows this stock commonly appears in builds configured with a pistol-length gas system and chambered in 5.56 NATO. Builders on GPP commonly pair this stock with the Phase 5 Weapon Systems Phase 5 Version 2 Extended Bolt Release, the Geissele Automatics SSA-E X Lightning Bow Trigger, and the Aero Precision Stripped M4E1 AR-15 Lower Receiver.
