MasterPiece Arms BA Ultra Lite Chassis Fixed Stock - Remington 700 Short Action - Green

Build the ultimate lightweight precision hunting rifle with the Masterpiece Arms (MPA) BA Ultra Lite Chassis. Tipping the scales at an astonishing 2.6 lbs in a fixed stock configuration, this ultra-lightweight chassis is purpose-built for mountain hunters, backcountry shooters, and long-range marksmen who demand chassis-level modularity without a weight penalty. Machined from 6061 billet aluminum and coated in a durable H-Series Cerakote finish, the Ultra Lite utilizes a unique internal pocketing architecture that eliminates unnecessary material while preserving high-rigidity structural integrity.

Designed around MPA's proven V-Bedding system—which incorporates extra clearance to allow optional action and barrel glass bedding—the Ultra Lite Chassis accommodates Remington 700 actions with rock-solid repeatability. The foreend comes equipped with an integrated Arca-Swiss RAT rail along the bottom for instant tripod mounting, a built-in bubble level, and multiple QD sling attachment points. Complete with an adjustable buttstock featuring embedded set-screw lockup for length-of-pull and cheek height, this chassis accepts standard AICS-pattern magazines to deliver maximum accuracy in a packable footprint.
