We have gushed over MasterPiece Arms (MPA) in the past, proclaiming that the rifle parts manufacturer’s products live up to their name. Their Bolt Action (BA) Chassis System, in particular, remains popular among the professionals. According to the ever-reliable Precision Rifle Blog, 27% of the top competitive shooters, an overwhelming majority, agreed.
To be more specific, they named the MPA BA Competition Chassis as their favorite chassis or stock of all. This system has been a fixture of the game since its introduction several years ago. However, a brand new and innovative MPA creation is giving it a run for its money: the Matrix Chassis. Here is some information on both kinds of chasses and the differences that distinguish them.
What Exactly are They?
The BA Competition Chassis is a variant of MPA’s iconic BA Chassis System, slightly retooled to enhance the long-range capabilities of competitive shooters. Its attachable “spigot mount” accessory extends the fore-end of the chassis, and its full-length Arca Swiss Rail can connect with both bipods and tripods. These dominant features elevate an already popular model into a must-have for present and future pros.
The Matrix Chassis is also based on the BA Chassis System, but it enhances the design with some brilliant innovations. Chief among them is the astounding variety of configurations for how your hand can hold the rifle. This unprecedented level of customization can make the difference between victory and defeat, and shooters who care about such intricacies may appreciate having these choices.
The Most Notable Differences
So, we have a chassis designed and revered for giving its users a competitive advantage, and we have a chassis designed for intense personalization of the shooting experience. The question worth asking is, how do they truly differ?
Fore-End
For starters, people can expand the length of the fore-end of their BA Competition Chassis if needed. They can enhance their rifle’s stability with the help of what Ammoland describes as “additional hole locations,” which help them access the “rotating barricade stop.”
The Matrix Chassis also offers holes on its underside for the barricade stop, but it adds something else on its sides: M-LOK slots. Also, for those who want as much length as possible, the fore-end has an extra couple inches on the standard BA Competition Chassis.
Grips
Let us return to the key feature of the Matrix Chassis: the customization of the grip and hand area. You can choose from two out of five unique grip options, one out of three distinct thumb rests, and any or all four trigger finger support designs. This means your personal chassis could have any of more than a hundred different configurations, perfectly suited to the way you like to hold your rifle.
With that said, not everyone really wants all these options. Precision Rifle Blog notes that the BA Competition Chassis’ “Enhanced Vertical Grip,” while not quite as innovative, still has its fans. Many professional shooters are satisfied with it, showing that simplicity is not always a negative.

Despite the notable differences mentioned above, the BA Competition and Matrix Chasses have plenty in common as well. They both have a pull-length between 13.5 and 14.75 inches. They both utilize Rapid Adjustment Technology (RAT) Rails. Cerakote finish, aluminum material, V-bedding system, and more are all common to the two systems. Most of all, they are designed and built with the high-quality standards of an outstanding industry titan.
