Randy,

It sounds like you own a Century International Arms assembled FAL parts gun. Century's "bread and butter" has always been buying foreign surplus weapons (and importing them for re-assembly into civilian legal configurations - usually with a replacement receiver).

Your rifle most likely was is the following:

* Assembled by Century.
* Consists of a mix of used parts (from various guns, country of origin, etc. For example you have an INCH pattern barrel and a METRIC pattern upper reciever).
* Was built on an Imbel (imported from Brazil) upper receiver.

THE BAD NEWS <img src="/ubbthreads/images/graemlins/thumbdn.gif" alt="" />

1) Century has never been known for quality control. In fact, they are known for the opposite.

2) Your parts might or might not have been in sound condition before Century refinished your "build".

3) You probably did NOT replace the necesarry foreign made parts to LEGALLY permit the conversion you described. Section 922r states that a firearm (made / imported after '89) cannot be comprised of more than 10 foreign made parts.

Per 922r the FAL has the following parts:

1) Magazine Body
2) Magazine Follower
3) Magazine Floor Plate
4) Receiver (Upper)
5) Barrel
6) Bolt
7) Bolt Carrier
8) Op Rod
9) Gas Piston
10) Hammer
11) Trigger
12) Sear
13) Muzzle Device
14) Buttstock
15) Handguards
16) Pistol Grip
17) Trigger Housing (Lower Receiver)

You can have any TEN of the above parts of foreign origin and be legal. However, the moment you introduce #11 you are in violation of manufacturing an illegal weapon.

THE GOOD NEWS <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />

A) It is nearly impossible to foul up a FAL build. Literally anyone can do it.

B) Your "Type 3" Imbel upper receiver is the heart of the rifle, and considered by many to be the best FAL reciever ever made.

C) You've owned it 15 years, and it hasn't gone KABOOM yet so you're likely okay.
