$2,999.00
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 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.
The ESR Rimfire Rifle is a combination of our ESR Competition Chassis along with an MPA/Curtis Action chambered for rimfire applications.
Available in a multitude of barrel profiles and muzzle threads, the rifle is setup specifically for PRS/NRL rimfire competitions.
The rifle will come standard with an ATS Barrel Tuner, along with a custom thread protector.
Because this rifle uses a standard Curtis Short Action “Action”, it can be converted over to a center fire rifle with the purchase of a centerfire bolt, barrel and magazine.
The barrel will use barrel nut system, giving the shooter the ability to adjust headspace, which can vary depending on the ammo being used by the shooter.
The chamber in this rifle is setup to run both Lapua/SK ammo and Eley ammo (different rim thicknesses) with similar bullet profiles. We also have the ability to chamber the rifle in other configurations based on the ammo you prefer to run. Please reach out with any questions.
We will also offer this rifle in either 1:12 or 1:16 twist rate. Lets us know if you need help in determining the correct twist rate for your application.
