Thumbhole Stocks, how many parts?

[edblevi]

I have an old FAL sitting around with the dreaded Thumbhole Stock from years ago and the ban. So if I want to take this off and put some regular furniture on it how many parts need to be US? I guess the correct question would be "how many parts does the Thumbhole stock account for"?

It's an old CAI receiver, L1A1 parts, some metric FAL.....one of those early FAL's that were hodge podged together by CAI.

Anyway thanks for the replies.

Depends who made the other parts, and if they're clearly marked MADE IN USA.

I believe you will need seven.

Most common I see for that is three piece furniture set, HTS, and brake all being US parts. If the receiver was made in the US, that will count as a part.

The thumbhole stock replaces 2 foreign parts.
You can only use 10 foreign parts from the ATF list.

From the list, should have 6 US parts without a muzzle device, 7 with.

Completely irrelevant to the “RKBA and Legal” topic, but has anyone here actually tried replacing the Century thumbhole stock with a conventional stock set?

Gunplumber notes in his book that Century ground off parts of the lower to fit the thumbhole, and that replacement (home or shop fabricated) parts have to be welded, soldered, or epoxied into place to make the conversion work. Otherwise, the only alternative is to replace the whole lower!

Sounds like a horrifying amount of work . . .

All you need is a bushing for the pistol grip to replace the bashed/ground/pried off PG bushing. Gunthings sells them.

Bushing/stud for pistol grip attachment to lower receiver. This bushing will fix a receiver with a ground off stud. Bushing is hollow for the pistol grip screw to pass through. Steel. $OUT

The diameter of the hole in the lower receiver, depth in the pistol grip, and a few minutes in a hardware store and you can roll your own.

You will also need a trigger plunger plate because they hack a retaining tab off the top of it and more than likely you need the plunger and plunger spring because both of mine had evidence of being dicked with.

ThunderGod and JasonB, your great advice is exactly what I was looking for. :bow:

I have a much better idea of what's involved now. Thanks!

One more...or maybe 2 more! Check (or just replace) the sear spring since I seem to recall both of mine having that part butchered as well and I am almost thinking one of mine was missing the trigger pin sleeve as well.

I do seem to remember one of my homemade bushings came from the plumbing section and the other came from the fasteners sections and I think the plumbing section was less hassle using a couple of sizes of pipe nipples and get them just barely oversized and you can turn them down with a file and a hand drill and it will work fine...or an actual lathe. :)

Good luck!

Looks like I'll be checking out the local Ace hardware store today. :D

Thanks again for your help. :)
