Yeah i realize the caliber difference I'm no newbie.
I just don't know if I can find a carbine short enough in .308. I can sacrifice big game capability if I can't find what I want.
DPMS makes one but I don't care much for it.
The front runner right now is Knight's SR-15 it's amazing.

I could also get a 6.8mm PPC carbine from DPMS for under $1k. Too bad that's a worthless caliber.
As far as your reccomendation of a heavy barreled model. I don't think it's necessary. A carbine can certainly provide servicable accuracy out to 400 yards. I'm not asking for 1/4 MOA accuracy or I'd be using my LTR.
Heavy barrel would kinda defeat my #1 purpose as well as portability.
I'll check out Rock River.
