"...the carbine is on EE here so I can't..." PM the seller and ask.
I had an authentic M1A para, and to make it non restricted it was going to require a barrel length of 19-1/4". If you are going to use a faithful replica of the para stock I would suggest that you would be looking at that barrel length.
I thought the barrel length on a non-restricted centerfire semi had to be 18 1/2 inches.
I've seen lots of ruger mini 14s fitted with folders that are still non-restricted, unless there is something on an M1 carbine action that I am missing...
The problem was that with the stock folded the rifle was not over the 26" length. It required the extra barrel length to get it there.
An aftermarket stock like a Chaote may not have this problem. But a decent replica of the military folder likely will. Installing the M1A stock on an 18.6" non restricted M1 carbine will technically make the gun prohibited.
Oh, okay. However, I'm under the impression that a firearm that can be reduced below the legal overall length by temporary means, such as a folder, and still be fired was restricted, not prohib.
If the rifle is presently non-restricted, and you modify it with the stock that now reduces it's total length to under 26", you have just made a prohib. The CC doesn't allow an individual to make a restricted out of a non-restricted.
You can work the other way though, and bring a restricted up to non-restricted status.
What if before mounting the folding stock on the non-restricted m1 carbine, you welded/pinned so that it would not fold, would that not make it the same as any other stock and therefore would meet the length requirements to keep its non-restricted status?
