Technical features
The Ruger Precision Rifle has a proprietary Pre-Fit barrel system. Pre-chambered "Drop-In Ready" barrels can be purchased, and the correct headspace is set using a proprietary barrel nut design. The barrel is threaded to fit the Ruger action threads. This way, a competent gunsmith only needs an AR-15 barrel wrench and proper headspace gauges to fit a new barrel.[14] This eliminates the need for machining by the gunsmith as with traditional barrel mounting solutions.[citation needed]
The RPR is compatible with AR-style handgrips, buttstocks and some types of handguards. The trigger is proprietary, but aftermarket triggers are available.[15]
The Ruger Precision Rimfire is a rimfirebolt-action rifle manufactured by Sturm, Ruger & Co. in the United States. The firearm has some visual similarities with the larger centerfireRuger Precision Rifle, and both are marketed as budget precision rifles.
