Masterpiece Arms builds World Class Rifles. We start with our industry leading Chassis System, utilize the Best Actions and Triggers produced, and our MPA/Spencer 416R Handlapped Barrels (or Proof/Carbon Six Carbon Fiber Barrels) provide some the best shooting, most accurate rifles in existence. Designed, Built and Enhanced by Long Range Shooters and Hunters, our Rifles fulfill the needs of the most discerning shooters.
These are estimated lead times set by MPA and are subject to change at any time at their discretion.
The MPA Hybrid Hunter is a purpose designed rifle for the long range hunter. Whether you are hunting in a tree stand, blind, or from the side of mounting, shooting off a tripod, the Hybrid Hunter can put the perfect shot on target.
The Hybrid Hunter starts with our light weight Hybrid Chassis and is matched with the Curtis Hybrid Hunting Action. The Hybrid is a technologically advanced and feature rich chassis system with several key features to help improve your hunting performance. This includes the MPA RAT rail, adjustable cheek riser, adjustable length of pull, EVG (enhanced vertical grip), inclinometer leveling system, and V4 spigot mount.
The RAT (Rapid Adjustment Technology) rail, also known as an Arca Swiss Rail, provides significant flexibility for direct tripod or bipod attachment anywhere along the length of the chassis forend. This is an extremely rigid setup that performs much better than a hog saddle or similar clamping devices. This system also gives the user the option to make quick, easy adjustments to the bipod or tripod position on the fly, which is crucial out in the field. For example, if the shooter has to build an improvised modified prone position on a rock, tree stump or other surface, the ability to rapidly adjust the location of the bipod maximizes flexibility for an ultra precise shot.
The adjustable Cheek Riser and Recoil Plate allows the user to fine tune the fit to their body type, length of pull, and preferred shooting configuration.
We can fine tune your rifle build to your specific application! This includes caliber, chamber dimensions, barrel length, contour, twist rate and chassis finishing. No matter what your long-range precision varmint hunting needs are, we can design a rifle to meet them!
