would galil bolt carriers fit into common ak receivers?
also,
1. to build an ak it must have 6 us parts?
currently available us parts that i was able to browse:
piston
muzzle brakes
complete trigger group (3pc)
pistol grip
receiver
stock (folding)
and if i weld a magazine then the floorplate and follower for it
You can only have 10 or less imported parts from the list. The edited (shortened) list for countable parts on an AK type rifle are the following:
(1) Frames, receivers, receiver castings, forgings or stampings
(2) Barrels
(3) Mounting blocks (trunions)
(4) Muzzle attachments
(5) Bolts
(6) Bolt carriers
(7) Gas pistons
(8) Triggers
(9) Hammers
(10) Disconnectors
(11) Buttstocks
(12) Pistol grips
(13) Forearms, handguards
(14) Magazine bodies
(15) Followers
(16) Floorplates
With the muzzle device that leaves you with 16 "countable" parts. Meaning that if I replace the FCG (3 parts), piston (1 part), receiver (1 part), and use a U.S. muzzle device (1 part) I am left with 10 imported parts and legal. I can also replace any of the other items such as the pistol grip instead of the muzzle device.
If you eliminate the muzzle device by removing the threads that leaves you with 15 "countable" parts. I only need to replace 5 imported parts to get to the magic number of 10. A muzzle device would be a brake (currently legal) or flash suppressor (legal after 9/14). The muzzle nut is sometimes refered to as a thread protector. The muzzle nut is not counted in the imported parts list, but 27 CFR does not define muzzle attachment. So use caution when deciding to use a muzzle nut. It may still be counted as an imported part at a later time.
With a milled receiver, the trunnion and receiver are combined into a single unit. This reduces the number of parts needed to make a compliant milled rifle with a muzzle device from 6 to 5. It reduces the number from 5 to 4 for a rifle without a muzzle device.
The easiest way to make sure your rifle is legal is to cross the U.S. made parts that you actually have in the rifle off the list. Then just count whats left. If you have 10 or less imported parts, you're legal. There is no point in replacing more than the required number of parts "just to be sure". U.S. made parts are marked as such. Anything not marked will most likely not be counted by the BATFE unless there is documentation to prove otherwise
Any part on the list that you actually make counts as a U.S. made part, including magazine bodies/parts. See below for additional magazine info. Make sure you take pictures or otherwise document the construction of parts you make.
Note: Trunnion is referred to by the BATFE as a mounting block for a barrel. As such, the U.S. made stock tang sold by JoeKen and others does not count toward the list. The stock tang is not a trunnion.

2. to have a folding stock it must have 10 us parts?
The presence of a folding stock is completely unrelated to parts count. The folding stock is covered by the 1994 Crime Bill, also called the Assault Weapons Ban (AWB).
The AWB states that you may not build a semi-automatic rifle that has 2 or more of the following:
Pistol grip
Detachable magazine
Folding stock
Flash hider/grenade launcher
Bayonet lug
Threaded muzzle
Since the AK type rifles typically have most or all the following "Assault Weapon" features, we have to eliminate all but 2 in a rifle we build. We usually keep the pistol grip and detachable magazine. That means anything else would be illegal.
After the AWB sunsets on September 14 12:01am, you can build a rifle that has all of these parts.
If you have a U.S. made folding stock that can be made non-functional (doesn't fold), you can use it in your build and it counts as a U.S. part. If the stock cannot be made non-functional, you can only have 1 other "Assault Weapon" feature. Most stocks can be made non-functional by replacing the mechanism spring with a steel tube or pinning the mechanism. As long as the folding stock mechanism cannot be operated by hand it is legal. Some parts of the mechanism can be replaced by a bolt, like the AMD-65 push button. As long as the bolt is tight enough that it can't be loosened without the use of a tool it's legal. You do not need to weld or permanently disable the folding mechanism. It just needs to be incapable of being hand operated.
The AWB also makes it illegal to manufacture magazines that hold more than 10 rounds (except for military or law enforcement use only). So if you build a magazine before Sept. 14 it cannot legally hold more than 10 rounds. After Sept. 14 you can build a magazine that holds as many rounds as physically and logistically possible.
The AWB has nothing to do with parts count. Even after the AWB sunsets, you will still have to comply with the parts count regulation. Bear this in mind if you install a muzzle device such as a flash hider/grenade launcher.

3. did i miss anything?
4. anything good/bad on Ace receivers for a beginer?
5. did Hesse ever make M16 magazine adapters, and did they work?
would appreciate your input
For the Ace or any other bent blanks, refer to the Silver Dollar (aka 7.62x39) tutorial on the Ace website.
http://www.acearms.com/tutorials/blank_build.shtml
When you start, measure the front of the blank. The front INSIDE height should be 1.200".
I'm not exactly sure what you're talking about for magazine adapters...
If you have questions, use the search function and if you can't find an answer, post away. There's lots of great advice here and the owners/mods are much nicer than those on other boards.
