Did these rifles come with any part 922r parts other than the thumbhole stock?

I just picked one up still new in the original box. Dated 1996...

Been so long since I had one can't exactly remember. Some have Century receivers. Personally I gave up caring about 922.

That was sort of my thought too actually but I was curious. It's got an Imbel receiver so that's good.

In a word, NO. I have one.

Ditto, and the OP wouldn't be manufacturing or assembling the rifle if he were to swap out the butthole stock.

Some came with a magazine bottom plate spring and follower. If you have a mag that doesn't work you may have one of these. They also original charging handles that had a big aluminum knob in place of the original. The trigger hammer may have a C on it. However I believe most never had the correct number of parts.

Some inch guns also came with a US made barrel. It wasn't threaded and it was too big around to be threaded without bein turned down
