For 2015, Gemtech has announced a revolutionary, patent-pending bolt carrier built for your suppressed rifle.

The all new SBC allows the user to choose between a suppressed and unsuppressed setting. The shooter can enjoy increased reliability without altering the gas block, buffer or any other components.

Normally shooters use gas-buster charging handles, heavier buffers and an adjustable gas block to fight an overpressured system, but Gemtech has pushed things into the next generation with the SBC.

Built of S7 Steel for lighter weight and faster heat dissipation, and for erosion resistance, Gemtech’s patented SBC is an adjustable, drop-in fit for your AR platform rifle.

An even greater advantage provided by the SBC is increased reliability, reduction of carrier speed and lower felt recoil. In fact, on full auto the SBC reduces cyclic route down to the same level as if the weapon was unsuppressed. Some tests have produced cyclic rates even lower, though individual weapons and experience will obviously vary.
