Masterpiece Arms BA Ultra Lite Chassis


After many requests from our customer base, MPA has developed the BA Lite Chassis.

At an astonishing 2.5 lbs with Custom recoil pad, the BA Lite will provide shooters who desire a lightweight rifle stock/chassis a feature rich design that will serve primarily hunting applications.

As with our BA Chassis, the BA Ultra Lite will provide the shooter with the ability to adjust the length of pull, cheek riser position, add side picatinny rails and other accessories, and also increase the distance from the spigot mounted bipod to the rear support. The MPA leveling system will be included as standard equipment.

The length of pull and cheek position are locked in place via set screws that are embedded into the buttstock body. It provides a very strong lockup of the cheek riser plate and recoil plate assembly.
