Released in 2006, the original JP AMCS(TM) chassis system broke the mold by porting over the superior AR ergonomics and interface to the bolt gun. After several years in the refining, the APAC(TM) chassis has arrived. This design draws from the real-world experience of our outstanding precision shooting team and collaboration with former U.S. Army sniper and precision shooter, Brian Whalen. The result is a chassis system developed by and for the most demanding precision riflemen, both in the military/LE communities and on the competition circuit. Industry-shaping JP design and precision manufacturing are brought to bear here to create the most durable, functional and solid s Mfg: J P Enterprises
