OMR Shouldered Prefit Barrels are 100% guaranteed to properly head space with factory configured actions and bolts for all listed actions. Our Carbon Fiber Shouldered Prefit Barrels are custom built to your specifications. All of our barrels have a magnum taper, which is 1” at the muzzle (Fits “Sendero Contour” stocks). Our barrels come threaded for brake, cap or suppressor. If you are running yours suppressed, most likely your suppressor uses the 5/8″-24 muzzle threads, so be sure to choose that option.
All OMR carbon fiber barrels start with 416R stainless, match grade, button rifled, hand lapped, and stress relieved blanks. Every blank goes through our rigorous inspection process for tolerances, craftsmanship and material imperfections. Match Grade bore must measure within .0005″ of our standard diameter and groove cannot vary in diameter more than .0003″ for the length of the barrel. Once a blank passes this inspection, only then will it get carbon wrapped using the same state of the art materials and techniques that are employed in the Aerospace industry. We do all this to ensure that our customers receive the stiffest, most accurate, carbon fiber barrel available on the market today.
Important Note About Trued Actions: OMR Shouldered Prefits WILL NOT work. Specifically, if you have had any of the following work performed to your action: the bolt face trued, action body trued or lug work, we cannot guarantee that your barrel will head space correctly. OMR Shouldered Prefits will not work without needing a Gunsmith to check assembly and proper head space and additional chambering and or throat work may be required at owners expense. Your best option is to start with one of our Carbon Fiber Blanks, and have your local Gunsmith chamber it to your action.
Easy to install:
- Use an action specific wrench along with a quality barrel vise to install your OMR barrel.
- OMR recommends to torque your barrel to 75-90 ft/lbs.
- Use caliber specific Go/NoGo gauges before and after tightening the barrel nut to ensure proper headspace. Can be rented from www.4Drendtal.com
