For the past eight years, it has been the preferred choice in the Precision Rifle Series (PRS), helping shooters achieve unprecedented success in competitive long-range shooting.

Unrivaled Performance in Competitive Shooting

Proven Track Record

The MPA Matrix Chassis is the most widely used and acclaimed chassis in PRS, renowned for its reliability and performance. It has consistently helped shooters win more 1 and 2 Day matches and dominate AG Cup Matches since its introduction, making it a proven leader in the field.

Revolutionary Design and Customization

  • M-Lok Compatibility: Features M-Lok slots along the fore-end for attaching a wide range of accessories.
  • Barricade Stops: Integrated holes on the fore-end enhance stability when shooting against barriers.

High-Quality Construction and Materials

Durable and Lightweight Build

  • 6061 Aluminum: The chassis is machined from a single billet of 6061 aluminum, ensuring strength and lightweight handling.
  • Cerakote Finish: A durable Cerakote coating in Flat Dark Earth not only provides a distinctive look but also adds extra protection against the elements.

Precision Engineering

  • MPA RAT System: Incorporates the Rapid Adjustment Technology with a 1.5″ Acra Rail, allowing for quick and precise adjustments.
  • V-Bedding System: Ensures optimal alignment and consistent accuracy.
  • Adjustable Buttstock: Features an adjustable cheek riser and length of pull for tailored comfort and stability.

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 in Flat Dark Earth is more than just a component; it's a comprehensive system designed to elevate the long-range shooting experience. With its proven track record, extensive customization options, and robust construction, it remains the top choice for serious shooters looking to maximize their performance and precision on the field. Whether competing in PRS events or engaging in tactical applications, the Matrix Chassis provides the reliability, adaptability, and precision required to excel in any shooting endeavor.
