Description

These Ruger Precision Rimfire barrels have a match chamber and crowned with an 11 degree target crown. The fact that these barrels are hand-lapped and that the internal diameters are on the tight side contribute to their extreme accuracy and make them a true target type barrel. Customers ask if any gunsmithing work is required to install these barrels. The quick answer is; no there isn’t. Below we have information describing the procedure to change barrels. It takes just a few minutes. Drop-in barrels are turned to fit the Ruger receivers and chambered in this Haas CNC lathe. We have a set of barrel break-in and cleaning instructions that we suggest for the 22 rimfire  and a printed copy is furnished with the new replacement barrel. Installation Instructions are below:

1. To remove original barrel, hold the barrel in a barrel vice, and unthread the barrel nut. (1-3/16″ wrench)
2. Pull original barrel out of receiver.

3. To install new barrel reverse the above procedure. The extractor slots will align the barrel, with the engraving at 90*
4. Retighten barrel nut against the shoulder on the barrel shank.

If you are having trouble sliding the shank into the receiver, check the extractor slots for a burr.
