The MPA BA PMR competition rifle is designed specifically for the production class requirements of the PRS series. It includes many competition related features. The length of pull and cheek riser position are adjustable and locked in position with a series of set screws that are embedded into the buttstock body. This is the same system we use on our standard BA chassis, but without the thumb wheels.
