The new Colt SP6940P is an advanced modular, 5.56mm, piston-operated, lightweight, one-piece upper receiver, magazine fed carbine capable of firing in automatic and semi-automatic modes. The Colt P0923 incorporates a unique articulating link piston (ALP) operating system that reduces the inherent stress in the piston stroke by allowing for deflection and thermal expansion. The P0923 is specifically designed for ease of cleaning, disassembly, and assembly of parts.

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.
