Mitchell Defense DualCool ARCA15 AR-15 M-LOK Handguard 15" Black

Overview

The Mitchell Defense DualCool ARCA15 is a dual-layer M-LOK handguard built specifically for AR-15 platforms. Measuring 15 inches in length and finished in black, it utilizes an engineered air-gap thermal barrier that separates the inner and outer shells. This dual-layer construction absorbs heat within the inner shell while keeping the outer surface cooler and safer to grip during sustained fire, while also accelerating cooldown between strings. Precision 3D-printed from CP1 aerospace alloy, the handguard delivers high strength, excellent corrosion resistance, and a high strength-to-weight ratio. It features an integrated ARCA rail along the bottom with centerline M-LOK slots, dimensioned and scalloped for both RRS and Area 419 systems to provide direct, repeatable mounting for bipods, tripods, and accessories without adapters. The unit includes the handguard, a platform-specific barrel nut, a handguard key, and two mounting screws.
