Masterpiece Arms Matrix Pro Chassis: A Revolution in Precision Shooting

Overview of the Matrix Pro Chassis

The Masterpiece Arms Matrix Pro Chassis represents the pinnacle of innovation in rifle chassis design, catering specifically to top-tier PRS/NRL competitors. This latest iteration introduces a plethora of customizable options, revolutionizing the shooter's grip with over 100 variations in grips, thumb rests, and trigger finger supports. The strategic placement of the shooter's hand near the rifle bore enhances shooting precision by allowing numerous personal adjustments to the chassis setup.

Key Features of the Matrix Pro

Advanced Grip Customization

The Matrix Pro Chassis's primary feature is its advanced grip customization, which offers unprecedented personalization through an extensive array of grips, thumb rests, and trigger finger supports. This flexibility ensures that shooters can fine-tune their grip to match their personal preference and shooting style, as demonstrated in the detailed preference data provided in the product visuals.

Integrated Comp Side Rails

For stability in improvised shooting positions, the Matrix Pro includes integrated Comp Side Rails. These rails not only support stable shooting with bag support but also feature a machined profile for the most rigid fore-end in PRS/NRL competitions, enhancing the chassis's overall steadiness.

Innovative Weight Tuning System

The chassis incorporates a unique internal and external weight tuning system. By shifting more weight towards the front and reducing it in the buttstock, the Matrix Pro allows shooters to precisely balance their rifle according to their specific needs and desired center balance location.

Extended Magwell Plate System

Each shooter can take advantage of the Matrix Pro’s innovative Magwell Plate System. These plates not only protect the magazine in various shooting positions but also enhance the chassis’s stability when using a rear bag, offering multiple configuration options to suit different shooting techniques.

Enhanced Fore-End and Quick Adjustments

The fore-end of the Matrix Pro is extended by 2 inches compared to its predecessor, featuring a simpler bipod removal system through the improved RAT RAIL. Additionally, the Quick Release Bag Rider adjusts the rear bag rider's height with the push of a button, offering flexibility in adjusting shooting elevation and platform requirements.

Standard and Optional Features

Standard Configuration

The Matrix Pro Chassis comes standard with:

  • Multiple grip and thumb rest options
  • An enhanced buttstock with an adjustable cheek riser and length of pull
  • M-Lok slots for additional attachments
  • A durable Cerakote finish available in various colors
  • Adjustable recoil pad and inclinometer leveling system

Optional Enhancements

Shooters can further customize their Matrix Pro Chassis with additional grips, thumb rests, and trigger finger supports available for separate purchase. For those opting for a specific aesthetic, a custom Gun Candy Color can be specified at checkout.

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 Pro Chassis is designed for the serious competitive shooter who demands the best in customization, stability, and precision. With its array of innovative features and customizable options, it stands as a leader in the evolution of competitive shooting equipment.
