TacFire® ACE 20 Series 15" Free-Floating M-LOK Handguard - Slim Ergonomic Profile, Full-Length Top Picatinny Rail, Steel Barrel Nut Included, Aircraft Aluminum Body, Anodized Matte Black Finish - HG20-15 / 686294505089
Product Description
Standard drop-in plastic handguards limit your accessory mounting options and apply unwanted barrel pressure that degrades long-range accuracy. Upgrading to a modern free-float setup isolates your barrel from hand pressure and bipod loads while giving you maximum real estate for grips, lights, and aiming lasers. The **TacFire® ACE 20 Series Free Floating M-LOK Handguard 15" Black (HG20-15 / 686294505089)** delivers a sleek, full-length handguard upgrade engineered specifically for 16-inch or longer AR-15 rifle builds.
Precision-machined from 6061-T6 aircraft aluminum with an anodized matte black protective finish, the HG20-15 measures 15 inches long to completely cover carbine, mid-length, or rifle-length gas blocks. It features M-LOK mounting slots along the 3, 6, and 9 o'clock positions for mounting grips, handstops, or weapon lights, alongside a continuous M1913 Picatinny top rail for seamless optic and iron sight alignment. Supplied with a heavy-duty steel barrel nut and mounting hardware, this free-floating handguard transforms your AR-15 upper receiver into a modern, highly functional shooting platform.
Designed for universal fitment on standard mil-spec AR-15 upper receivers, this 15-inch free-float M-LOK handguard provides lightweight strength and modular accessory staging straight off your workbench.
*Armorer Bench Notes & Real-World Staging Guidance: The TacFire HG20-15 handguard arrives complete with its propriety steel barrel nut and anti-rotation mounting screws. RECEIVER & BARREL FITMENT MATRIX: Fits standard **mil-spec forged and billet AR-15 upper receivers**. *Gas Block Note:* Requires a low-profile gas block to clear the internal diameter of the handguard on carbine, mid-length, or rifle-length gas systems. Workbench Setup Steps: 1. Always verify your upper receiver is completely clear of live ammunition before starting work. 2. Remove your existing barrel nut and gas block. 3. Install the included steel barrel nut onto the upper receiver threads, torquing to 35-50 ft-lbs using a barrel nut wrench. 4. Slide your low-profile gas block and gas tube into position on the barrel and secure set screws. 5. Slide the 15" ACE 20 handguard over the barrel nut assembly, align the top Picatinny rail with your upper receiver rail, and torque the clamping screws evenly to lock the handguard securely in place.*
