[ARCHIVED THREAD] - Ruger mk III upper, I think

Posted: 10/12/2012 6:23:49 PM EDT

With threaded barrel.
I bought this planning to suppress it. After scanning these threads I thought I'd better ask if this upper will work on either of the ruger lowers: mk2 and 22/45? I have both guns.
Also, I wish I'd bought a lower when they were being sold for $100 or so!
