I'm thinking of getting a 9mm AR style carbine. I have a bunch of 9mm ammo and want to use it for 3 gun, hunting, plinking. I want it to be able to hit 4" circles at 60-70 yards.

I presently have a Kel-TEc, BUT it is going back to KT as it won't run. If it doesn't run, or isn't accurate enough, the above is the next plan. I haven't shot it enough to evaluate it. I was told that they are accurate and reliable enough...we'll see.

What sort of platforms would work? Olympic has one that uses Sten mags. Rock-R has one that uses Uzi mags (which I like better than Sten mags) and Lone Wolf makes a lower that uses Glock mags...what else is there and what are your thoughts?
