No flies on the 7600 IMHO. We bought this one years back for my brother, who is a lefty. It has been used quite a bit. Barrel is to long for my taste. 20" should be plenty for the .308 Win.
No problems encountered - feeding and extracting is fine. Accuracy easily good enough for the hunting the rifle is used for (note the 2,5x Weaver).
I also have a Rem. 750 Carbine in .30-06. They have changed the magazines. The follower now actes as bolt stop.
