Aero Precision Inc 12.7 inch MOD-4 Minimal Optical Deflection Handguard

Description
MINIMAL OPTICAL DEFLECTION (MOD) 4 HANDGUARD

The Aero Precision Minimal Optical Deflection (MOD) 4 Handguard seamlessly blends robust construction with an ergonomic form factor, ensuring no compromises between the two. Machined from 6061-T6 aluminum, the handguard is engineered with a focus on stiffness to drastically reduce deflection under load. It attaches to the upper receiver via a steel barrel nut, significantly reducing point-of-impact shift when using an infrared laser aiming device under load.

In addition to its premium engineering, the MOD 4 Handguard offers several quality-of-life improvements. A full-length, 7-sided M-LOK™ interface allows the user to customize their build according to their preferences. The steel-reinforced QD sockets enhance strength and ensure longevity when used with standard steel QD sling attachments. Installation is simplified at the barrel nut, eliminating the need for timing, and the lug pattern matches mil-spec castle nuts—no specialty tools required. Two anti-rotation set screws add redundancy and a tailored fit when used with third-party upper receivers.
