Hoss:
Right. FN was a plant in Belgium where the FAL was designed and produced. I has been built around the world, and is currently still manufactured in Brazil and Argentina, at least.
AR may or may not be ArmaLite. Armalite and Eugene Stoner designed the AR-10, AR-15, AR-18 and a whole bunch of other weapons. They sold the rights to the AR-15 to Colt, who made a ton of money off of it.
5subslr5 is an AR/Armalite trivia nut and can put you to shame with the details he knows.
Currently, ArmaLite (formerly Eagle) makes one of the AR-15 clones, along with Colt, Bushmaster, Olympia, etc.
DSA makes their receivers and some of their guns here in the US. Their bargain line (the STG-58) is made from Austrian Army rifles which were torn down prior to import due to our countries' arcane firearms laws and EOs. Like potato chips (or pork rinds) Once you start, you just gotta have another of a different configuration. I just sent you to FalFiles and DSA cause you wanted to know about FN-FALs.
Going with .223 (or 5.56) first is a great idea. The Bushmaster shorty is a fine item. But then you'll need a 20" A2, then an A1, then an M-4gery, and some mags, and a couple of optics, and mounts, oh yeah, a RIS or RAS, and LOTS of ammo, bwaaaahaaaa! Another addict, hooked!
For what it is worth, the FAL is actually cheaper to get started, cause the rifle is the same $ to a little more, but the mags are MUCH less.
Good show in Raleigh. Look for Ed's Guns. His prices on new are usually the best. Then come back here for all of the goodies you will need for it!
Hoss, if you think that's a cow, you haven't spent much time around them, either. Sheep can be gooooood friends. And they're shorter than cows, too!
