PWNolan is who made mine.GM all. Busy morning at the CC.
Did manage to order a 3-pack of 10-rd 10/22 mags on sale at PA for sub $45with shipping. In all my reading last night the mag/feed problem in 93's is quite common. No aftermarket support, only "bend feedlips" fixes. I may go the way of 1-shot conversion....calling those that recently upgraded. Who did you get those from?
He's on Ebay and Rimfire Central.
