Re: who makes a 223 bolt rifle with a 1 in 7 twist
Buy a custom action with the 700 footprint, whatever flavor of stock you like, and put a 1:7 on.
Otherwise, if you need to go the repeater route, you're limited to a ar15 upper with a 1:7 twist barrel (fairly common), for now.
Unfortunate this is a go big, or go home, moment
