MPA Ultra Lite Chassis

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

At an astonishing 2.6 lbs with Custom recoil pad, the Ultra 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 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.

Notice on Inlets: Our Chassis with the Remington 700 Inlet in Short action configurations fit all Remington 700 actions and clones including but not limited to the following: Bat Machine HR & VR, Bergara, Curtis Axiom, Curtis Vector, Curtis Helix, Defiance Deviant, Defiance Rebel, Defiance Elite, Stiller Tac series, Bighorn TL2, Bighorn TL3, Lonepeak Arms, Kelbly Atlas Tactical, Ga Precision Templar V2, GA precision Tempest, Impact 737R, Surgeon SA & LA (Except Surgeon XL)

The V-Bedding system is also configured to allow the ability to glass bed the action and straight section of the barrel if desired.

The Ultra Lite Chassis will accept AICS Style 5 & 10 Round Magazines, plus the 3 Round Magazines from Hawkins Precision and Others.

Custom Cerakote Colors add $135 for the chassis. Check with MPA for all the custom colors available.
