Own a Ruger Precision Rifle (RPR)? Looking for the single best hardware upgrade that will improve inherent accuracy and shot-to-shot consistency? Here’s your answer. Krieger Barrels is now producing Pre-Fit barrels for the RPR in seven popular chamberings: 6XC, 6mm Creedmoor, 6.5 Creedmoor, .243 Win, 6.5 PRC, .308 Winchester, and .300 Win Mag. These $550.00 “Drop-In Ready” barrels come finish-chambered and threaded to fit the Ruger action. The Ruger barrel attachment system allows correct headspace with a pre-chambered barrel. Krieger explains: “Thanks to Ruger’s proprietary barrel nut design, a competent gunsmith will be able to swap out your barrel using an AR15 barrel wrench and proper headspace gauges.”

Kreiger’s 6.5 Creedmoor RPR barrel is an 1:8″-twist with 26″ finished length, 0.750″ at muzzle. The .308 Win RPR barrel is a 1:10″-twist with 24″ finished length, also 0.750″ at muzzle. Both these Krieger RPR Pre-Fits feature muzzles with factory-spec thread so you can re-install the factory muzzle brake.
