Colt Alternative Operating System

Piston technology is nothing new for us here at Colt. In fact, it was our company that was the first to put a piston system into an AR platform in the late 1960’s to meet a US Army request. The Colt Model 703 was born. Again, Colt was the first to produce this new wave of AR piston systems over 40 years ago…and we’re doing it even better now.
