MasterPiece Arms is a very familiar company to any PRS (precision rifle series) shooter. They make some of the most popular chassis systems in the game due to the fact that they are packed with features and customizable to a user’s preference. New for 2020 is MPA’s Matrix Chassis.
The Matrix is extremely modular; available with three different thumb rests that vary from 20-45 degrees, four different sized trigger-finger supports and six different grips that come in vertical or swept angles. In total, there are at least 100 different configurations!
The Matrix is available for three different inlets; Remington 700 short action, long action, and Tikka short action. This pretty well covers what people choose to put in chassis.
One minor detail that you may pick up on when looking at the Matrix is the cutout behind the grip. Many of you would mistakenly take this to be a thumbhole to stick your thumb through and grip the chassis while shooting — but that is not what it was designed for.
The Matrix is not a thumbhole stock, rather it is there to make the rifle easier to move in a secure manner when changing from stage to stage during a competition or while switching between shooting positions.
Another nice feature on the Matrix is the butthook. This cutout on the bottom of the buttstock allows the shooter to apply rearward pressure, further stabilizing the rifle while shooting.
Besides swapping out the different components of the Matrix, you can also adjust the gun to fit your body perfectly though the use of the adjustable cheek piece and recoil pad. With these, you can customize length-of-pull, cant, and cheek-riser height.
Other small details that you may overlook on the Matrix Chassis are the RAT (Arca swiss rail) rail machined into the forend, Spigot mount which accepts Arca Swiss or Picatinny-style bipod attachments, and the night vision bridge.
I am super excited about this chassis and I look forward to completing a full review. Keep an eye for one coming in the future on GunsAmerica.
Pricing starts at $1,250 for the Matrix. Check out MPA’s website HERE for more information.
