OMR carbon fiber Prefit barrels are compatible for your Ruger American rifle.  Our barrels start with match grade stainless steel blank, and carbon fiber wrapped to our precision standards.  Available in all Ruger American factory calibers in lengths of  18" - 28".  All of OMR's barrels have a magnum taper, which is 1” at the muzzle (Fits into all Sendero Contour stocks).  

These barrels will require a Ruger American barrel nut (not included).  Threaded for brake, cap or suppressor at 1/2”-28 , 9/16"-28, or 5/8”-24.

All OMR carbon fiber prefit barrels start with match grade, button rifled, hand lapped blanks. Every blank goes through our rigorous inspection process for tolerances, craftsmanship and material imperfections. 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 You, our Customer the lightest, most accurate carbon fiber barrels available on the market today. 

Easy to install:

  • OMR recommends to torque our prefit barrels to 75-90ft/lbs.
  • Use caliber specific Go/NoGo gauges after tightening the barrel nut to ensure proper headspace.  Can be rented from www.4Drendtal.com
  • Once you have installed your new OMR barrel, it is recommended that you have the caliber engraved or stamped before use.  OMR does not do this prior to shipping, because we have no idea where your barrel will time out and properly headspace.
