The rifle is constructed on the company's MPA Tactical Chassis System, which is CNC machined from 6061 aluminum and features a specially designed V-bedding system that provides room for a glass-bedded action. The chassis includes a number of high-end elements that are perfect for long-range shooters, such as a built-in level, thumb notch, MPA Enhanced Vertical Grip and several sections of Picatinny rail located on the top and bottom of the chassis. The entire system is finished in a Cerakote coating for a custom look and added durability.
Attached to the chassis is the company's buttstock design, which includes custom-adjustable length of pull and comb height, allowing owners to build a precision fit for the best possible comfort. The adjustable components are secured in-place through several screws integrated into the chassis design, ensuring a solid lock-up. The stock also incorporates a built-in monopod that enables shooters to build a solid position.
Set inside the chassis system is a Remington-700-style Curtis Custom Axiom Long Action, which is then mated to a Spencer/MPA Heavy Varmint barrel machined from 416RQ stainless steel. The barrel measures 26 inches long and can be had in either a 1:9-inch or 1:10-inch twist rate. The muzzle end is threaded with a 5/8x24 TPI thread pitch and includes an MPA Muzzle Brake for enhanced recoil control. The action also includes a Curtis Spiral Fluted one-piece bolt, finished in a Diamond Like Coating for enhanced durability.
The MasterPiece Arms MPA .300 Norma Bolt-Action Rifle is fed using single-stack, common-pattern, long-action magazines designed by a company that makes such things. One five-round magazine is included with the rifle. The gun also comes equipped with a custom Trigger Tech trigger that's adjustable from 1-3 pounds. The weight of the chassis system is 5.35 pounds. The suggested retail price on the new MPA .300 Norma Bolt-Action Rifle starts at $3,275.
