The Geissele Automatics GDP 5.56 8" M-LOK Black pistol is a compact AR-style platform built around an 8-inch cold hammer forged, chrome-lined barrel and a 7" MK16 M-LOK free-float handguard. It features Geissele’s Phased Array gas system with Tri-Port tuning, a Nanoweapon-coated HUXWRX Flash Hider QD 5.56, and the dual-telescoping GDP pistol brace for a stable, adjustable shooting interface.

This GDP pistol is chambered in 5.56 NATO / .223 and uses a semi-automatic action optimized for smooth recoil and reliable cycling from a short barrel. The ergonomic A17 reduced-angle grip, SSA X trigger, Airborne Charging Handle, Super Configurable Safety, and Maritime Bolt Catch make it well suited for home defense, training, and range use where a maneuverable, high-quality AR pistol is desired. Geissele’s reputation for precision machining and premium components is evident throughout this GDP build.
