MasterPiece Arms Matrix Chassis: The Pinnacle of Precision in Long-Range Shooting

Introduction to MasterPiece Arms Matrix Chassis

The MasterPiece Arms Matrix Chassis, particularly designed for the Remington 700 Long Action and finished in an eye-catching green, has set a new benchmark in the world of precision shooting. Renowned for its revolutionary design and versatility, the Matrix Chassis has become a favored choice among top long-range shooters and has consistently dominated competitions within the Precision Rifle Series (PRS).

Dominance in Competitive Shooting

Proven Track Record in PRS

In the rigorous arena of PRS, which serves as a proving ground for the finest rifle equipment, the Matrix Chassis stands out as the most popular choice among competitors. It has secured more victories in 1 and 2 Day matches as well as AG Cup Matches than any other chassis system since the series began. This track record is a testament to the chassis's superior design and functionality that enable shooters to hit more targets and achieve greater success.

Revolutionary Design Features

Customizable Interface for Optimal Control

The Matrix Chassis offers an unprecedented level of customization with over 100 different options for grips, thumb rests, and trigger finger supports. This extensive customization ensures that each shooter can tailor the chassis to their specific ergonomic needs, improving comfort and control.

  • Grip Options: Includes six choices (three Swept and three Vertical), allowing shooters to select the grip that best fits their hand size and shooting style.
  • Thumb Rests and Trigger Finger Supports: Three thumb rest options and four trigger finger support options enhance shooter comfort and rifle stability.

Enhanced Structural Features

  • M-Lok Slots and Barricade Stops: The chassis includes M-Lok slots along the sides for mounting accessories and barricade stop holes on the bottom of the fore-end for enhanced stability during shooting.
  • Extended Fore-End: Provides an additional 2 inches of length compared to previous models, offering more space for hand placement and accessory mounting.

Advanced Engineering for Superior Performance

Precision Machining and Materials

  • Constructed from 6061 Aluminum Billet: This high-strength material ensures durability and stability without compromising weight.
  • Cerakote Finish: A durable Cerakote coating protects the chassis from the elements and enhances its aesthetic appeal.

Adjustable and Ergonomic Features

  • MPA Buttstock: Comes with an adjustable cheek riser and length of pull, which can be fine-tuned from 12.75 inches to 14 inches, or reduced to 12.5 inches upon request.
  • Recoil Pad: Adjustable for height and cant, providing enhanced comfort and recoil management.
  • Built-In Features: Includes a bag rider with a butt hook and a V4 Spigot Mount, integrating both a Picatinny rail and a dovetail plate.

Compatibility and Specifications

  • Magazine Compatibility: Fits any AICS type magazines for both short and long action calibers, with magazines available for purchase separately.
  • Weight and Dimensions: The chassis weighs 6.4 lbs, with a fore-end weight of 3.35 lbs and a buttstock weight of 2.85 lbs. Overall length is 36.6 inches, with a fore-end length of 14.0 inches and a max barrel diameter of 1.250 inches.

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 Matrix Chassis is more than just a component; it's a comprehensive solution for serious long-range shooters. Its proven track record in competitive scenes and its highly customizable features make it the top choice for shooters aiming to maximize their precision and performance. Whether for competition or practice, the Matrix Chassis offers the ultimate in reliability and accuracy, solidifying its status as the gold standard in precision rifle chassis systems.
