Sorry, no personal experience with AutoOrd's M1 Carbines, but I did own one of their semi-auto Thompson M1928s about 15 years ago. If those were any indication of their quality control, then you would be far better off finding yourself a USGI M1 Carbine. The new-manufacture Thompsons were horrible. Nice external finishing/bluing, but the internal machining and fitting were by far the worst I have ever encountered. The action was like sand-paper, I cut myself repeatedly on internal burrs and sharp edges while cleaning the upper receiver, etc. Not to mention that the striker-fired action resulted in a trigger-pull exceeding 25 lbs....
When I finally acquired a CA USGI Thompson M1A1, the difference was night and day. The action was like glass, the machining was superb, etc. Auto Ord's quality-control quite evidently went way, way down-hill following WW II.
My advice would be to stay away from Auto-Ordnance products. Unless their new ownership by Khar Arms has somehow resulted in current-production items that an order of magnitude better in terms of craftsmanship. Honestly - the older Auto-Ord stuff is abject crap. It looks pretty, but it is crap.
FWIW as a former Auto-Ord owner,
