Masterpiece Arms MPA Matrix Rifle Chassis

Masterpiece Arms Chassis have been the gold standard for Long Range Shooters for the past 8 years. In the PRS, which is the testing ground for the best rifle equipment produced, the MPA Chassis is the #1 Chassis (used by the most shooters), won more 1 and 2 Day matches and the most AG Cup Matches since the series inception. Our Chassis Technology is market leading, allowing shooters who run our chassis to hit more targets, win more matches, and harvest more trophies.

The Matrix Chassis is the most revolutionary chassis ever produced. With the multitude of configurations in grips, thumb rests and trigger finger supports, the primary interface between the shooter and the rifle (the grip) has over 100 different options. (Please refer to the photos above to see our data on shooter preference on the grips, thumb rests, and trigger finger supports). The location of the shooters hand – closer to the bore of the rifle – provides even more variety on how the shooter can set up the chassis.

Swept 2 – For those with larger hands who prefer a swept grip

Swept 3 – For  those with medium hands who prefer a swept grip

Swept 4 – For those with smaller hands who want their hand/fingers closer to the trigger and also prefer a swept grip

Vert 1 – For those with larger hands who prefer a vertical grip.

Vert 2 – For those with medium hands who prefer a vertical grip. Closest to the EVG in size and feel. 

Vert 3 – For those with smaller hands who want their hand and finger closer to the trigger and prefer a vertical grip.
