The OMR Action Wrench will not break. It does't come with a so called, "breaking point" like other cheap wrenches claim. OMR starts with 416 stainless bar stock, which is then inserted into our stare of the art 4th axis mill to be precisely machined to .002" of an inch. OMR uses a duel lug design which provides 2X's the surface area support in the raceway which eliminates any chance of side torque.
Your barrel and any of the following items you order (examples: muzzle brake and/or thread protector) will be cerakoted in your choice of color. We DO NOT cerakote the carbon fiber on your barrel, just the steel portions.
Your entire barreled action and any of the items you order with your OMR Shouldered Prefit Barrel, examples: muzzle brake and/or thread protector, will be cerakoted in your choice of color.

Description

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.  

The 3A thread fit (highest classification) has no allowance and smaller tolerances than the class 2A thread fit, resulting in a tighter fit ensuring proper muzzle device alignment. 

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.  OMR guarantees 1/2 MOA with all our barrels.

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
  • Disclaimer of Liability:  Oregon Mountain Rifle Co assumes no liability for damage and or injuries that result in whole or in part from improper installation, product malfunctions, negligent, criminal, improper use, and reloaded or defective ammunition.

If you are not comfortable installing your Shouldered Carbon Fiber Prefit, please contact your local gunsmith and make sure they will do the install for you. If you or your gunsmith is not able to install the Prefit Barrel, please select the “OMR Prefit Barrel Installation” option at the checkout.  We will gladly help you with this.
