I have a early Varmint Kevlar in .223 (Ackley now) with the 12 twist barrel. Its a neat little gun, and has piled up more coyotes than I can count. The trigger is pretty good, and the gun isnt a bugholer, buts its plenty accurate.
The integral scope bases pretty much suck, but a DIP rail fixes that. The safety is a non issue...it works exactly as designed. The set trigger is a neat concept, but real world usefulness is questionable. The magazines are one my favorite parts. Lots of folks complain about them hanging down, and many cut them for the 3rd mags. If I had my way, I would buy ten rounders to run in it. The mags give you a little more room than an AR magazine, and are very thin and easy to carry.
