Anything made in USA counts I think.
Not exactly. There's a list. Some things count, others don't.
(1) Frames, receivers, receiver castings, forgings or stampings
(3) Barrel extensions
(4) Mounting blocks (trunions)
(5) Muzzle attachments
(7) Bolt carriers
(9) Gas pistons
(10) Trigger housings
(15) Butt stocks
(16) Pistol grips
(17) Forearms, hand guards
(18) Magazine bodies
(20) Floor plates
If it's a US made part on that list, it counts. Note that butt stock, pistol grip, and forearm/hand guards are listed as 3 separate entries, so, 3 parts.
The FAL contains 17 parts in that list (assuming a flash hider or muzzle brake) and there's a maximum of 10 foreign made parts allowed (means you have to have at least 6 [or 7 with muzzle device] US made parts on the FAL), any more than that and you can go to federal prison.
Would the stock count as 1 part?
Buttstock = 1 part
Pistol Grip = 1 part
Fore end = 1 part
In other words, the entire "furniture set" is 3 parts.
So, it would be a reduction of 3 parts to have that installed. I believe that there is a kit somewhere designed especially for the Century Arms models, the last time I checked into it they were somewhat pricey.
I'll have to dig out BTP "Gun Bible" he had a long list of the parts that were made in America.
Either way, that has to be done soon, when the 08 "elections" roll around it may not be possible to even buy a pricey kit, let alone actually install the thing.
Better him then me.....I favor the Cetme.
My understanding is that the thumbhole stocks were installed to circumvent the law, but if he installs a standard US made buttstock and pistol grip, he has 2 US made parts right there. TAPCO used to sell a compliance kit that was a US made furniture set (buttstock, pistol grip, handguards) and a hammer/trigger/sear set that covered 6 of the required parts for about $100. I don't think the set is offered any more, but you can still get US made furniture sets and an FSE (or Entreprise) HTS kit and get 6 of the required parts. Not as cheap a way to go about it, but it works. The gun is probably built on a Century receiver, which would make 7 and should put him into the safe zone nicely. Of course, if the gun was a Century build to begin with, it should contain the correct number of US made parts, and if he replaces their sear with an Entreprise sear, he'll still be good to go without changing parts count.
