The MPA Matrix Chassis delivers tremendous versatility for shooters.

MasterPiece Arms recently announced the release of its next chassis system, the MPA Matrix Chassis. Built upon MPA’s popular BA Chassis System, the MPA Matrix Chassis delivers a multitude of configurations in grips, thumb rests and trigger finger supports. Moreover, the grip provides more than 100 different variations for the shooter.

MPA developed a hand measurement chart to help identify which grip configuration works best for each individual shooter. Additionally, the location of the shooter’s hand, closer to the bore of the rifle, provides even more variation in how the shooter can set up the rifle. The MPA Matrix Chassis feature five different grip options. It includes three different thumb rest designs and four different trigger finger supports. It also features M-LOK slots along the side of the chassis forend and barricade stop holes along the bottom of the forend. The forend of the chassis comes the same length as the MPA ESR Chassis, making it tow inches longer than the standard BA or BA Competition Chassis.

MPA Matrix Chassis Features

“One of the things that we have seen in precision rifle shooting over the past couple of years is how many different methods a shooter used to engage a stock or chassis,” said Phil Cashin, President, MasterPiece Arms. “Due to variations in hand size, finger thickness and length, as well as shooter preference on how they want to engage the chassis or stock, we’ve seen a lot of inconsistencies amongst the shooters in how they engage the rifle and where they position the pad of the trigger finger with the shoe of the trigger. This inspired us to create a system that would provide a more custom fit procedure for our customers by creating a chassis with more customized configurations.”

MasterPiece Arms machines the chassis on the company’s CNC Horizontal Machining Centers to exacting tolerances from 6061 aluminum. The MPA buttstock comes with an adjustable cheek riser and length of pull, recoil pad with height and cant adjustment. It also features an adjustable cheek riser and adjustable monopod (bag rider on Competition Model). The v-beddign system provides additional clearance for glass bedding action and straight section of the barrel if desired.
