I just wanted to say that the little Remington 7615 5.56 pump carbine pretty much rocked. We took it through all the hoops, from shooting off the bench to speed drills on steel to the infamous Gunsite Rifle Scramble course, and it just kept on ticking.
I'm sufficiently impressed to say the 7615 may be the ideal rifle for a civilian self-defense scenarios — easy to shoot, uses readily available AR magazines, not and "assault weapon," light weight. I could go on, but you really need to shoot one. They should be in the civilian pipeline within a couple of months.
BTW, wait 'til you see my "out" at the end of the SHOOTING GALLERY episode on this gun (and carbine shooting in general)! I'd just finished a run through the Scramble (and a pretty good run, if I do say so myself), and I'm a pathetic whipped puppy.
