New for 2018: McCutchen Firearms .50 BMG MF-50 Upper Receiver


The beauty of the AR-15 platform is the ease with which any number of compatible upper receivers can be mounted onto a single lower receiver, opening up the possibility to have a truly multi-caliber system built on a single serialized rifle. Many companies have taken this concept to extremes, and the latest to build big on the AR lower is McCutchen Firearms, offering its .50 BMG-chambered upper receiver that's ready-made to mount on any mil-spec AR-15 lower receiver.

Na, mostly think it’s cool. Don’t think I can safely even shoot one around here.
