M157 Bufferless Gun Mount

The M157 is a bufferless gun mount and is for use with the M2HB/M2A1/M2A2 series .50 caliber machine guns, as well as the MK19 40mm grenade launcher. With optional adapters, the M60 series, M240 and M249 machine gun variants can also be used.

The M157 provides reduced weight and increased weapon reliability through a “bufferless” design, which mitigates mount-induced harmonic interference, given a recoil-operated weapon system.
