The Aero Precision minimal optical deflection (MOD) 4 handguard delivers the perfect combination of durable construction and ergonomic design, offering both strength and comfort. Machined from premium 6061-T6 aluminum, this handguard is engineered for maximum stiffness, effectively reducing deflection even under heavy load. It securely attaches to the upper receiver using a steel barrel nut, which plays a crucial role in minimizing point-of-impact shifts when using infrared laser aiming devices. Designed with the shooter in mind, the MOD 4 handguard features a full-length, 7-sided M-LOK interface, allowing for easy customization of your build. The steel-reinforced QD sockets ensure exceptional strength, preventing premature wear when paired with steel QD sling attachments. Installation is made easy with a barrel nut that requires no timing and the pattern aligns with mil-spec castle nuts, eliminating the need for special tools. Additionally, two anti-rotation set screws ensure a precise and secure fit, making it compatible with third-party upper receivers. The MOD 4 handguard stands out as an essential upgrade for any build, offering unmatched performance, ease of installation and customization options.
