TacFire A.C.E. High Profile M-LOK® Handguard — 15", Black Hardcoat Anodized Aluminum, for .308 Win AR-10 (HG20HP30815 | UPC 686294505492)
Build a large-frame AR that feels modern, rigid, and ready for work. The TacFire A.C.E. High Profile M-LOK® Handguard delivers a 15" free-float rail in black hardcoat anodized aluminum, engineered for .308 Win AR-10/DPMS-pattern rifles that use high-profile top-rail height. With rock-solid barrel nut engagement, abundant M-LOK real estate, and a continuous Picatinny top, HG20HP30815 gives you the strength and mounting flexibility to run lights, lasers, sling QD mounts, bipods, and night-capable optics—without front-end bulk.
Why Choose the A.C.E. High Profile 15" Handguard
True Free-Float Accuracy: Keeps sling, grip, and accessory pressure off the barrel for more consistent point of impact.
15" Length, Maximum Usability: Extended rail space for barricade work, night setups, and optimal light placement past suppressor shadows.
High-Profile Top Rail: Matches DPMS-pattern high-profile uppers, promoting seamless alignment from receiver to handguard.*
Light, Strong, Rigid: Precision-machined aluminum with Type III hardcoat anodizing stands up to heat, hard use, and the elements.
M-LOK Everywhere You Need It: Slots at 3/6/9 (and often the 45° facets) simplify cable routing and accessory placement without adding weight.
*Always verify your upper receiver’s rail height (high vs. low profile) before purchase.

Installation Tips (Non-Instructional)
Verify Rail Height: Confirm your upper is DPMS high-profile.
Prep & Fit: Degrease, then install the included barrel nut per torque specs; confirm alignment for the gas tube.
Mount Handguard: Slide on, square to the receiver rail, and torque cross-bolts to specification.
Clearance Check: Ensure gas block and muzzle device clear the inner diameter; cycle the action to verify no contact.
Final Pass: Add M-LOK accessories with proper torque and threadlocker where recommended.
Care & Maintenance
Wipe Down after rain/dust; the hardcoat finish cleans easily with mild soap and water.
Hardware Check after the first range session; re-torque mounting screws as needed.
Avoid Harsh Abrasives to preserve the anodized finish and laser-marked indices.
