I think your choice is dependent upon what distance you want to use your "tac driver". If you're limited to 100 yd targets, ANY model 10, 11, 12 in 223 is going to be very accurate. And if cost is a factor, the 12FV with a no hassle, bolt it on laminate stock, scope and mounts will cost less than a grand ready to shoot. My son's is able to produce 5 shot groups in the high ones at 100 yds.

If you truly want a turn key tac driver, you'll probably want the 12BVSS. Mine was shooting under 1/3 moa right out of the box. But it's a 9 twist, so the heaviest bullet it'll shoot is the 77 gr Nosler CC or 77 SMK.

I've shot mine out to 750 yds with the 69 grain SMK and it would bang steel consistently at that range.
