Ruger Single-Six "old model" mag. cyl.

Member Posts: 25 ✭✭
I am missing the .22 magnum cyl. for my "old 3-screw" Rugar single-six. I know that originally these were a return-to-factory fitted part. I have recently written to Rugar about this but in the meantime, does anybody know if they can still fit a new cylinder? Also, if they can't, what is the danger in buying a magnum cyl. on the open market? (Assuming I could find one.) Presumably Ruger had a good reason for wanting to fit the cylinder at the factory. Thanks.

It is still a factory/factory authorized
fit up. There could be issues with a cyl bought alone.
First is timing,It may not time and align properly.
Second, There are slight dimentional differences from one production run to the next. This due to revisions and refinements done along the way. The gun serial number tells them what parts fit up to you're particular revolver. These I've noticed are changes in cyl axis pin diameter, chamber spacing changes from very early samples and later old models. Of course, new model singles six's are vastly different.
usnrlcdr: I have a 3 screw 5 1/2" with just the 22 mag cyl. no way in heck that its going back to Ruger , if I want to shoot 22lr I just use a different gun [:D]
You will need to check the timing and the cylinder to barrel alignment. The cylinder must lock into position at the moment of hammer fall. With the gun unloaded, draw the hammer back and hold it, depress the trigger and check the lockup. If ok, work the action while observing the cylinder stop in the gap between the bottom of the cylinder and the frame cylinder recess. In a well-timed gun, the the stop will come up and latch the cylinder just as the next chamber comes into alignment. It will not touch the cylinder until the relief cut in the cylinder is directly above it.
A range rod can check the alignment. This tool is a bore diameter rod which is inserted into the barrel and all the way into the cylinder to the recoil shield. It should go all the way back on each chamber without resistance. Anyone with a lathe can easily make one of these, or they can be purchased from a gunsmith tools supplier.
