Aero Precision MOD 4 12.7″ Handguard, Black

Description

The Aero Precision Minimal Optical Deflection (MOD) 4 handguard is engineered for stiffness and modularity in modern AR builds. Machined from 6061-T6 aluminum, the handguard is designed to minimize deflection under load and to provide a stable mounting platform for accessories. It secures to the upper receiver using a steel barrel nut intended to reduce point-of-impact shift when using infrared laser aiming devices under load. The MOD 4 includes a full-length 7-sided M-LOK interface and steel-reinforced QD sockets for durable accessory and sling attachment options.
