As Johnny says, the stock triggers are just about the worst triggers you'll find on anything claiming to be "modern" in any definition of the term.
If you're lucky, you'll get a receiver with all the holes pre-cut (Trigger popping out through the pistol grip hole, and the stock trigger hole covered with a plate) and all you'll have to do is remove some spot-welds. Mine shoots like a dream.
Just an FYI, last I checked Classic Arms had a couple .308 veprs in stock. With those you don't even need to convert 'em.
