RE: Help with a ringed OS 50Sx
Steve:
The 50 SX ring, as stated by several above, is pinned. If you force it the liner, piston, and ring are immediately converted into junk. OS prices being what they are, once you do that a new Magnum 52 is a far better deal.
If you get everything lined up properly it will slide together easily and give you more good service.
Bill.
