Entreprise Arms

If you study an exploded diagram of a FAL, you will notice that the FAL does not have all of the parts listed above. It does have 17 of them though, and those parts are listed below.
1) Frame
2) Barrel
3) Muzzle attachment
4) Bolt
5) Bolt carrier
6) Gas piston
7) Trigger housing
8) Operating rod (in reality this is the charging handle and not an op-rod but that's how our government sees it)
9) Trigger
10) Hammer
11) Sear
12) Buttstock
13) Pistol grip
14) Handguard
15) Magazine body
16) Magazine follower
17) Magazine floorplate So, since the FAL has only 17 of the banned, imported parts and you can only use 10 parts, you must substitute seven of those parts listed above with domestically produced parts if you want to assemble a FAL from an imported kit. Below is a listing of the U.S. made parts that are most readily available and represent probably the lowest cost.
1) Receiver
2) Muzzle brake
3) Gas piston
4) Pistol grip
5) Trigger
6) Hammer
7) Sear There is another way to comply with the law that is a little less expensive but it has one drawback. You can assemble the rifle using the first five parts listed and substitute a U.S. made magazine floorplate and magazine follower instead of using the U.S. made hammer and sear. This will

be less expensive but technically, the rifle would only be legal as long as the magazine remained inserted into the magazine well. For some folks, this does not present a problem, I'll leave that decision up to you. Brownells carries the following, U.S. made parts from Entréprise Arms: Gas Piston (#292-000-006), Hammer (#292-000-007),Sear (#292-000-008), Threaded (~/16-24 LH) Muzzle Brake (#292-000-009), Magazine Follower (#292-000-010), Magazine Base Plate (#292-000-011). There is one other thing that you need to remember. If you are building a FAL and using a foreign-made receiver, like the FN-licensed receivers from Imbel of Brazil, you will need to substitute one, additional part. My suggestion is to use a U.S. made pistol grip because that will be the least expensive additional part. If money is not a criteria for your FAL-building project by all means substitute domestically-produced parts as your funds may allow. So far, this equation is quite simple but you must add the 1994 Assault Weapons Ban to the 1989 Importation Ban to get the complete picture.

1994 Assault Weapons Ban
The September 13, 1994 Assault Weapons Manufacture Ban listed the FN/FAL and all of its variants as an Assault rifle that could not be manufactured because it was capable of accepting a detachable magazine and it contained at least two of the following items or "points":
1) A folding stock
2) A pistol grip that protrudes conspicuously beneath the action.
3) A bayonet mount
4) A flash suppressor or barrel that is threaded to accommodate a flash suppressor.
5) A grenade launcher. This import piece of legislation will limit you, to some degree, in the way you will be able to assemble a FAL. I will get to the particulars and other aspects in Part II.
