So I have an Auto-Ordnance M1 Carbine that was given to me.



It was in very good shape, but didn't know the history of when it was purchased, etc.



Few issues seem to plague me and want to figure out how best to attack them.



First, it does not cycle reliably.  It will often go single shot.  



Most of the times, it will not go into full battery.  The bolt will strip a round from the magazine and feed it into the chamber, but the bolt itself is not in battery, and when you pull the trigger, just get a click.  Not sure if this is due to a crappy quality magazine or what.  Also, I've noticed that the rear action screw that connects the receiver to the stock, is loose a lot, even after tightening it repeatedly, I have not used lock-tite on it yet.



Third, the stock itself has a slight crack in it.  Near the handgrip area.  Not sure if this would cause the cycling problems, but it's there nonetheless and not sure what issue it would cause, if any.



Any help or suggestion would be greatly appreciated.  I've thought about just selling it off, but it would make a great truck gun, and I'd love to get it feeding reliably.

Not familiar with this manufacturer, but if you can switch out USGI Parts, so much the better.  The Recoil plate screw sounds messed up.  If you can replace the part with USGI, that may help.  Again, if someone that is more up to speed with the commercial copies, chime in...

I have had one for years now and have had no issue with my rifle ever.  Great little gun.

Try putting a little clear fingernail polish on the screw threads.  Much easier to break loose than locktite when you need to.  Before your reassemble, clean it off with fingernail polish remover.  I've been using it for years, especially on sight screws.

Also, are your using reloads?  I didn't know it until about a year ago, but carbine brass needs trimmed.  I had a few failures to chamber in my Inland, and when I broke the rounds down the brass was too long.

The little gas piston or " tappet " is held in place by a " lock ring" that screws into the " gas cylinder " part of the barrel .  Check & see if this is tight & clean .  I think Uncle Sugar staked the " lock ring " in place to prevent it from un-screwing .

    Check & see if the recoil spring or the slide / op-rod assembly are binding ?

    Does the bolt close OK on an empty chamber ?

    If you drop a dummy round into the chamber , does it go in far enough to let the bolt close 100% ( bear in mind the extractor will have to snap over the back of the brass ) .

    Is the chamber CLEAN ?

    Does it do this with all mags , or just some ?

    I agree , if you are shooting reloads , you need to check & trim the brass as needed .

    I FL resize the brass with a Lee carbide die .

God bless
