Fn Mk 46 Mod 1
The 5.56x45mm Fn Mk 46 Mod 1 is the lightweight U.S. special operators’ variant of the Fn M249 Saw .
The MK 46 MOD 1 incorporates improved receiver pins, a feed tray with retention pawls and a vented hand guard with improved heat shield and three MIL-STD-1913 rails. The MK 46 MOD 1’s cold hammer-forged MIL-SPEC barrel has a hard-chromed bore for longer life and improved accuracy, and serves as the mounting point for the carry handle.
The receiver is formed steel and is equipped with a top-mounted MIL-STD-1913 optical rail. A hydraulic buffer greatly reduces recoil, helping the operator keep more rounds on target. The crossbolt safety and curved trigger help enhance operator control. Includes one spare barrel.
