Battle Arms Development 9.5" Workhorse M-LOK Free-Float Handguard for AR Rifles - Black
Battle Arms Development
The Battle Arms Development 6.70" M-LOK free-floating handguard is built for shooters who want a lightweight, slim-profile rail system without unnecessary bulk. Designed to work on AR-15 and AR-10 platforms, this handguard strips away weight where it doesn't matter while keeping the features that do—a combination that makes it equally at home on a range gun, a hunting rig, or a dedicated precision build.
Made from 6061-T6 aluminum and finished in Type 3 black hardcoat anodize, the handguard uses skeletonized mounting areas to minimize weight without compromising rigidity. The design keeps a full MIL-SPEC Picatinny rail on top for optic-mounting flexibility, while M-LOK slots at the 3, 6, and 9 o'clock positions let you attach lights, grips, and other accessories exactly where you need them. The free-floating design isolates the barrel from the handguard, which can help tighten groups if your shooting setup allows.
At 6.70 inches, this length balances quick handling with enough rail real estate for your preferred accessories. Installation is straightforward with standard barrel-nut attachment—Battle Arms even provides torque specifications to keep things properly secured. If you're swapping out a heavier factory handguard or building an AR that needs to stay nimble, this is a no-frills option that delivers.

Yes, the Battle Arms Development 6.70" handguard is designed for both AR-15 and AR-10 rifles. It installs using a standard barrel nut (torque to 30-45 ft-lbs) and requires standard M-LOK-compatible accessories for any attachments.
Yes. The full-length MIL-SPEC Picatinny rail on top accepts any standard Picatinny-mounted optic, laser, or other rail accessory. The M-LOK slots on the sides and bottom let you add lights, grips, and other gear without cluttering the top rail.
A free-floating design isolates the barrel from the handguard, so hand pressure on the rail doesn't affect barrel harmonics. This can improve precision if your shooting technique and setup support it, though the benefit varies based on your specific build and shooting style.
Yes. The skeletonized design with material removed where it's not needed, combined with the notch-cut Picatinny rail, makes this a lightweight option compared to full-profile or heavy-duty handguards.
