APAC Chassis

Released in 2006, the original JP AMCS™ 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™ 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 shooting platform available today. Fully ambidextrous and collapsible, the APAC™ meets the needs of the most uncompromising shooters the world has to offer.
