I have an FN FNC. It's a very nicely made 5.56, Belgian made semi-auto rifle. However, the $3,000+ price tag for one of these is not worth it if you just want a great quality semi-auto 5.56 rifle. I'd say that about $1,000 of the price is premium due to the fact that there are still registered sears out there looking for semi-auto hosts. So, unless you have a sear, or know where to buy a registered sear, FNC is too expensive for what it is. You could find a good used SCAR-16s in the $2000+ range.
.......After doing a little checking and rethinking this, I no longer think that $2,500 of the FNC was "full-auto" premium, but after seeing what the SCAR's are selling for and what the all-swiss Sig 550 series rifles are selling for, the FNC isn't that far off the mark for a good European made 5.56 piston/folding rifle. Given that the FNC is no longer made, importable, excellent quality, and a full-auto host, it's probably a good value at 3K!
