Battle Arms Development AR-15 6.7" Workhorse M-LOK Handguard - Black Anodized

Battle Arms Development AR-15 6.7″ Workhorse M-LOK Handguard – Black Anodized

The Battle Arms Development AR-15 6.7″ WORKHORSE M-LOK Handguard delivers a compact, lightweight solution for AR-15 builders and shooters looking for high performance without the extra bulk. Designed for MIL-SPEC carbines with shorter barrels or pistol-length builds, this handguard provides a rock-solid mounting platform while preserving maneuverability and balance.

Engineered with M-LOK slots at the 3, 6, and 9 o’clock positions, this handguard ensures plenty of mounting real estate for accessories such as weapon lights, sling attachments, or handstops. The strategic skeletonized cutouts in non-M-LOK areas reduce unnecessary weight, keeping your build agile and responsive. At the top, the 1913 MIL-SPEC Picatinny rail remains full-length, giving you a continuous mounting surface for optics, BUIS, or other top-mounted accessories. The notched-cut profile of the rail ensures it aligns seamlessly with Battle Arms upper receivers, providing a sleek, unified look while also reducing material weight.

Measuring just 6.7 inches in length, this model is ideal for pistol-caliber carbines, SBRs, or lightweight CQB builds where compact size and fast handling are critical. Despite its small footprint, it maintains structural strength and compatibility with low-profile gas blocks. The internal diameter of 1.36 inches accommodates most modern setups, ensuring broad compatibility.

Constructed from durable, aircraft-grade aluminum and finished in a hard coat black anodizing, the 6.7″ WORKHORSE Handguard is built to withstand rigorous use while maintaining a clean, tactical appearance. Each handguard includes a matching barrel nut and the required mounting hardware, streamlining installation and minimizing the need for extra components.
