The TacFire A.C.E. M-Lok Handguard 4" Black Hardcoat Anodized Aluminum for AR-15 is a compact, free-floating accessory designed to modernize short AR-15 builds. Machined from 6061-T6 aluminum and finished with a Class 2 Type III black hard anodize per MIL-A-8625 standards, this ACE 20 Series M-Lok handguard delivers a rigid, lightweight platform with clean lines and generous M-Lok slots for accessories.

With its 4-inch length, this handguard is well suited for pistol-length or ultra-compact AR-15 configurations where maneuverability and minimal bulk are priorities.
