Aero Precision Inc 12.7inch MOD-4 Handguard

The Aero Precision Minimal Optical Deflection (MOD) 4 Handguard combines robust construction with an ergonomic design, providing maximum stiffness to minimize deflection under load. Machined from 6061-T6 aluminum, it attaches via a steel barrel nut, reducing point-of-impact shift when using infrared laser aiming devices. The MOD 4 features a full-length, 7-sided M-LOK™ interface, steel-reinforced QD sockets, and two anti-rotation set screws for a secure fit with third-party upper receivers. Installation is simplified with a barrel nut that eliminates timing and matches mil-spec castle nuts.
