FAL. DSA. New. Warranty. Extremely well built right here in the good old USA, and, should you need it, their customer service is excellent. After that I'd look at a kit build by one of the well known makers, Arizona Response Systems (I've owned one, no two, anyway, Mark does first class work), Arizona Expert Arms, Investment Grade Firearms (I've owned one, Jayson also does first class work), Ohio Rapid Fire (also owned one, Todd also does first class work) and a few others. Go over to the falfiles.com and ask them to rank the makers.
While my vote is for an FAL, if you're looking at SAR-8s...be absolutely sure to get the Greek made version (also owned one)....even if it costs you more money. The Greek made rifles are exact copies of HKs and were licensed by HK. The American version of the SAR-8 was not. I'd go with an ORF HK clone before a Springfield SAR-8. Springfields "lifetime" warranty isn't your lifetime, it's the lifetime of the rifle.
If they can't repair it, and remember they no longer stock parts, they offer you credit toward an M1A.
