Designed as a replacement upper for your standard Sugar Weasel or for whatever Frankenstein build you can think of. This upper receiver is paired with a 13", 1/2-28 threaded, tapered 5.56 barrel and our adjustable gas block with carbine length gas system.
The Strike Industries Mass Driver Compensator (MDC) represents a quantum leap in compensator design. Current designs have largely been unchanged since the 1930s. Its about time for something revolutionary. The Mass Driver name is inspired by the idea of theoretical mass driver engines in space travel. By ejecting mass, an equal and opposite reaction is generated propelling the space vehicle forward. The Mass Driver Compensator is driven by the hot gasses expelled through the barrel after the round is discharged, and acts as a counter balance system to attenuate mechanical recoil.
