Will Ruger replace the barrel/receiver on my Ruger .22 pistol?
We cannot change the barrel size or type of your Ruger .22 pistol. The barrel/receiver is an integral unit and can only be replaced with one the same size, type and finish as the original. It is serial numbered and is considered to be a ‘firearm’ by the BATFE. Barrel/receivers are factory fitted on an exchange only basis. The complete pistol must be sent to our Service Department for this service. It is recommended that you contact us prior to sending your pistol to the factory for a barrel/receiver replacement at 928-778-6555. The Ruger Mark I and Mark II pistols are no longer in production and barrel/receiver replacements for them are not available. The barrel/receiver for the Ruger Mark III pistol is factory-installed and is not sold separately.
