MasterPiece Arms BA Ultra Lite Chassis in Flat Dark Earth: Precision and Portability for the Dedicated Hunter


The MasterPiece Arms BA Ultra Lite Chassis, now available in a tactical Flat Dark Earth finish, is specifically designed for hunters and precision shooters who prioritize mobility without sacrificing performance. Weighing just 2.6 lbs with a custom recoil pad, this chassis system embodies a feature-rich design that caters primarily to hunting applications, though its versatility also extends to other precision shooting disciplines.

Features and Design

Lightweight and Strong

  • Material and Construction: Machined from 6061 aluminum billet, the Ultra Lite Chassis provides exceptional strength and durability while maintaining a light frame, crucial for those who navigate challenging terrains or require extended periods of carry.
  • Weight: At only 2.6 lbs (non-folder version), this chassis system significantly reduces the overall weight of the firearm, enhancing the shooter's endurance and mobility in the field.

Customization for Optimal Fit

  • Adjustable Cheek Riser and Length of Pull: Shooters can easily adjust the cheek riser and the length of pull (ranging from 12.75″ to 13.75″), ensuring a custom fit that can be further modified for shorter lengths upon request.
  • V-Bedding System: Allows for optional glass bedding of the action and the barrel's straight section to improve accuracy through enhanced stability and reduced harmonic vibration.

Enhanced Functional Features

  • MPA RAT Rail: Incorporates an Arca Rail on the bottom of the fore-end for easy attachment of bipods and other accessories, expanding its utility in various shooting setups.
  • Lower Picatinny Rail and Multiple QD Sling Swivel Locations: Offers additional customization options for mounting various tactical accessories and slings, tailored to the specific needs of the user.

Durable and Aesthetic Finish

  • Cerakote Finish: The chassis is treated with a high-quality H Series Cerakote in Flat Dark Earth, not only providing superior corrosion resistance and durability but also offering a visually appealing aesthetic that blends well with natural environments.

Compatibility and Specifications

  • Magazine Compatibility: Compatible with AICS style magazines for short action, including 5 & 10 round capacities, and also accommodates 3.850 length AICS style magazines for long action applications.
  • Comprehensive Inlet Fit: Designed to fit the Remington 700 Inlet in short action configurations, compatible with a wide array of actions and clones such as Bergara, Curtis Axiom, and Defiance series.

Detailed Specifications

  • Overall Length: 28.25 inches provides a compact yet effective platform for precision shooting.
  • Fore-End Length: 9.6 inches, ample space for comfortable hand placement and accessory attachment.
  • Max Barrel Diameter: Accommodates up to 1.200 inches straight, with a barrel channel width of 1.275 inches, allowing for substantial customization in barrel selection.

Immediate Availability at Bullet Central

For those looking to acquire the Matrix Chassis without delay, Bullet Central offers an appealing option as the chassis is available in stock today. This immediate availability allows shooters to bypass the typical manufacturing lead times and get their hands on this advanced chassis system right away. Purchasing from Bullet Central can be especially advantageous for competitors or hunters who need to prepare their gear without the constraints of a lengthy waiting period.

Extended Lead Times at MasterPiece Arms

Conversely, ordering directly from MasterPiece Arms entails a much longer wait. Currently, the lead time for receiving a Matrix Chassis from MPA is about 20 weeks. This delay is primarily due to the high demand and meticulous manufacturing processes that ensure each chassis meets the highest standards of quality and performance. While purchasing directly from the manufacturer ensures that you're getting a product straight from the source, the extended lead time might not be suitable for those who need their chassis ready for an upcoming season or event.


The MasterPiece Arms BA Ultra Lite Chassis in Flat Dark Earth is engineered for the hunter and precision shooter who demands a lightweight, highly customizable, and robust platform. With its advanced features and ergonomic design, this chassis is ideally suited to meet the challenges of both the hunting trail and competitive shooting, providing a tactical advantage in any scenario. Whether for long stalks in rugged terrain or precision shots on the range, the BA Ultra Lite Chassis stands as a top choice for those who refuse to compromise on performance and portability.
