M4, AR-15 MK4 M-LOK 15” .223/5.56 Rail - black

CNC aluminium forearm for M4 with M-LOK system. The NSR was designed with the goal of being the lightest and smallest free floating forend option to the M16 family of weapons.

Additional RIS rails (not included) can be attached to the forearm in any position using locks. The forearm is referred to as floating because it is only screwed to the receiver at the rear with a nut (which is inside the forearm). The forearm can be supported by a metal ring in the front, but this is not a requirement as it is already screwed to the receiver sufficiently. Likewise, there is no need to have a front sight block on the barrel. If you use a red dot, then the barrel just loosely passes through the forearm and is topped with a flash hider.

Forearm length is 15" (approx. 38 cm).
