I have had my Scar for two months and have dropped about 250 rounds through it. You can not shoot this gun without smiling. This is quite possibly the most enjoyable gun I have ever fired.
I love that the charge handle can be moved to either side. by moving the charge handle to the left side, I can charge the weapon without taking my shooting hand off of the pistol grip making mag changes and tap racks easier. Of coarse I have never had to do a tap rack.
Of coarse the best part about my Scar is that the gun is really clean. After a day of shooting, the chamber is no dirtier than my bolt actions.
If I could change one thing with the gun, it would be the trigger. At 6-7 pounds, this is obviously a battle trigger and not a target trigger. I have found a drop in trigger online that improves the trigger pull but that will have to wait.
