Guntec USA Ultra-Lightweight Thin M-LOK Black - Free Float Handguard - 15"

The Guntec USA Ultra-Lightweight Thin free float handguard fits tightly against the mil-spec upper receiver, providing a monolithic top rail that eliminates any gap or step between the upper receiver rail and the handguard rail — installed over the included proprietary steel barrel nut and secured with six mounting screws. Built for mil-spec AR-15 upper receivers, this free float handguard delivers a slim, ultralight M-LOK platform in a 15-inch black format.

The Guntec USA Ultra-Lightweight Thin is a 15-inch free float M-LOK AR-15 handguard featuring a monolithic top rail that mates tightly with the mil-spec upper receiver, installed over an included proprietary steel barrel nut and secured with six mounting screws, in a black finish.

The tight fit against the mil-spec upper receiver creates a monolithic top rail — a continuous, uninterrupted Picatinny surface from the upper receiver rail through the handguard without the step or gap that can occur when a handguard top rail does not align precisely with the receiver rail. The six-screw mounting system over the proprietary steel barrel nut provides the secure, stable attachment that a free-float handguard requires for consistent performance. The ultra-lightweight and thin design philosophy keeps the handguard profile slim and the overall weight minimal. M-LOK slots across the 15-inch body give full modular accessory mounting flexibility.
