Stern Defense MOD4 8" M-LOK Handguard - Anodized Aluminum

The Stern Defense MOD4 is a precision 8" M-LOK handguard built for the AR-15 platform. Machined from aircraft-grade aluminum and protected by an anodized finish, it provides a lightweight, rigid platform for mounting accessories along the full length of the rail system.

M-LOK slots along the sides and bottom accept a wide variety of lights, lasers, vertical grips, bipods, and other mission-specific accessories, allowing the shooter to configure the rifle for any role. The slim, low-profile design adds minimal weight while maintaining the strength required for hard use in the field or on the range.

Designed as a drop-in replacement for factory AR-15 handguards, the MOD4 pairs cleanly with standard upper receivers and barrel nuts, making it a straightforward upgrade for builders looking to add modern M-LOK accessory compatibility and a clean, contoured look to their rifle build.
