MasterPiece Arms (MPA) introduces the next generation of chassis, the Matrix Professional Chassis. The new Matrix Pro Chassis has evolved to meet the demands of the precision long-range market and is designed with the top-level Precision Rifle Series and National Rifle League competitors in mind.

“Over the past several years, the competitive landscape of precision long-range shooting has changed dramatically. MasterPiece Arms has always been committed to developing new technology to give the shooter a better opportunity to hit more targets. Since 2015, our MPA Chassis have been the number one chassis in the PRS, and 2021 was an especially good year,” commented Phil Cashin, President of MasterPiece Arms.

He continued, “however, the shooting market continues to change and become more complex and difficult and so the equipment must continue to evolve to meet these demands. No other company within this long-range competitive market has continued to lead with new technology as much as we have at MPA. So, with that said, we are proud to present the Matrix Professional Chassis, our continued commitment to this endeavor.”

The primary interface between the shooter and the rifle (the grip) has over 100 different variations, thanks to a multitude of configurations in grips, thumb rests, and trigger finger support options. The location of the shooter’s hand is closer to the bore of the rifle on the chassis and provides even more setup choices for the shooter.

The Matrix Pro Chassis features integrated comp side rails that provide a stable platform when shooting from improvised positions using a bag for primary support. The fully machined profile of the forend provides 60 percent more stiffness than the first-gen Matrix or ESR chassis. It is simply the most rigid forend ever created for PRS/NRL style shooting. The extended forend is also two inches longer than on the first-gen Matrix. The exit point on the Matrix Pro RAT RAIL (Arca Rail technology that MPA invented in 2015), now offers a simple exit point for removing a bipod during a stage. Simply slide the bipod off the front of the chassis.

The Matrix Pro Chassis offers each shooter four interchangeable plates that are mounted in front of the magwell that can protect the magazine during positional use or enhance stability when shooting with a rear bag.

The Matrix Pro Chassis has been redesigned to include a larger hole in the buttstock, while the buttstock itself is thinner in order to shift weight from the buttstock to the chassis fore-end. The chassis also uses a unique internal and external weight tuning system, and has a thin profile cheek riser that allows the shooter’s head to get more into the rifle. These features allows each shooter to fine-tune their balance point based on his or her specific rifle configuration and desired center balance location and gives the Pro an exceptional range of weight balancing options.

The Quick Release Bag Rider on the buttstock adjusts to the height of the rear bag rider with a simple press of a button, giving more flexibility to the shooter when engaging targets at a variety of elevations or if the shooting platform requires changes to the rear bag height.

MPA has developed a hand measurement chart to help identify which grip configuration may work best for each individual shooter. The MPA Matrix Pro Chassis features six different grip options (three swept and three vertical), three different thumb rest designs, and four different trigger finger support options. It also has M-LOK slots along the sides and bottom of the chassis fore-end, an enhanced buttstock design with butt hook, and comes with a standard or enhanced night vision bridge. The Matrix Pro Chassis will come equipped with the steel version of the V4 Spigot Mount out front, providing both rigidity and additional weight for weight balance.

The MPA Matrix Pro Chassis is machined on MPA’s CNC Horizontal Machining Centers to exacting tolerances from 6061 aluminum. The MPA-produced buttstock comes with an adjustable cheek riser and length of pull, recoil pad with height and cant adjustment, and adjustable cheek riser. The v-bedding system provides additional clearance for glass bedding action and straight section of the barrel if desired.
