Competition shooters are used to replacing the factory bolt hold open latch. This Volquartsen Posi-Lock Bolt Latch will replace the factory latch and withstand thousands of rounds and years of shooting. By contacting the bolt in a more effective way, this latch ensures the bolt locks open each and every time on an empty magazine.
Firearm Fit: Ruger MKII and MKIII (does not fit the 22/45 models)
