Kit's are kind of tough to find nowadays, and are a little on the expensive side. But, you can find deals out there. Honestly, a better resource for FAL info is the FALfiles... you might be able to get a kit for a decent price off the classifieds there as well.
Building an FAL is not much harder than putting together an AR. Once you have the barrel installed/timed and the head space set... the rest is assembly, just like an AR. If you fish around here/there you might be able to find a fellow enthusiast who's local who's tools you can utilize. Otherwise you'll need head space guages and some kind of barrel wrench minimum. I believe it's 7 compliance parts needed ?? Lot's of U.S. parts available out there. DSA, gunthings.com, FSE are a few vendors.
