The Aero Precision minimal optical deflection (MOD) 4 handguard perfectly combines rugged construction with a sleek, ergonomic design, offering the best of both worlds. Crafted from 6061-T6 aluminum, this handguard is specifically engineered for superior stiffness, minimizing deflection even under heavy load to ensure optimal performance. It attaches to the upper receiver through a steel barrel nut, which not only strengthens the connection but also reduces point-of-impact shift, especially when using infrared laser aiming devices. The MOD 4 handguard is thoughtfully designed with several key enhancements to improve user experience. Its full-length, 7-sided M-LOK interface offers versatile customization, allowing you to configure your build to your exact specifications. The inclusion of steel-reinforced QD sockets ensures durability and longevity, preventing wear when used with standard steel QD sling attachments. Installation is made easier with a barrel nut that requires no timing and its mil-spec castle nut compatibility eliminates the need for special tools. To further enhance security and fit, the handguard features two anti-rotation set screws, providing a snug, reliable fit when paired with third-party upper receivers. Whether you are upgrading an existing rifle or building a new one, the MOD 4 handguard delivers exceptional performance, strength and flexibility.
