Iver Johnson carbines:

[floydthecat]

I'd never even consider an Iver Johnson in any caliber as a substitute for a GI carbine either, nor any commercial copy for that matter. They were/are as GI compatible as most of the early commercials were/are. I think that if you want one to occasionally shoot and have, a $400-or-less investment in a Plainfield copy that you can improve with GI parts may not be a bad idea.
