I'v got a 6731 thats about 5-6 years old. I don't get the the range as much as I used to, but, I really like this gun: I put a jp trigger in mine, the trigger is now 3.5 lbs. the trigger has been in since about 1 year after I got the gun, never had any problems with it. I occassionally shoot some 3 gun competitions, and have almost always come in 1st or 2nd in the rifle stages anyway. I don't attritribute that to my skill, but the gun is quick handeling, and what I consider extremeley accurate out to 250 yards or so any way. I can put pop cans on the rail at 225 yards, and hit 20 in a row, with the right ammo. (as fast as I can get on target and shoot), we don't generally have a lot of competitors, about 9-14, and one guy shoot an HK PSG, He's only come close to me once. I don't think I'v ever had a malfunciton related to the gun, a couple because of poor ammo, but not because of the gun. I know there are lemons in evything made, but mine aint!! Good Luck.
