I just purchased this Century Arms FAL for $800. Came with six 20rd magazines, Condor "Tactical" sling, forend rail, and twenty five rounds of Lake City 7.62x51mm NATO. I haven't shot it. Everything is nice and tight on this rifle and the finish is excellent. Just a few dings in the stock and a little parkerization is worn from where the charging handle is.
Anyways... some pics and explanations.
The receiver has the following on it. The IMBEL Gear logo followed by...
RECEIVER MADE BY IMBEL - ITAJUBA - BRAZIL
C.A.I. GEORGIA, VT[/CENTER]
On the upper rear (just below the rear sight) of the lower it has a serial number of 226527
The serial number on the IMBEL receiver is FAL14XXX. What's interesting is that "FAL" is done by electric dot and the numbers are not and "FAL" is just off line and is not aligned with the numbers. It appears that the "FAL" part of the serial number might have been added after the receiver was made and the numbers were struck. The numbers are in the same font as the information stamped on the receiver.
Inside of the magwell it's stamped "2004".
The IMBEL receiver is marked "Cal. 7,62mm (.308)". The lower has the following selector markings. "S", "R", "A". No other marking are on the lower. The selector switch will not move past the "R" but I am not sure if this is due to the selector switch itself or simply the pistol grip.
The rear sight is graduated from 200mm to 600mm.
The front sight post has "0", "4", "8", "12" stamped on it. The gas selector has no markings on it.
There is an "A" stamped on the gas plug.
There are no other marking on the rifle. I took the forend off and there are no markings on the barrel. The bolt carrier is stamped with a number that does not match anything else.
