I am getting different answers from different sources on this, and finding all kinds of different charts on the liner twist rates for the Superior and Superior Heavy Liners in .30/700mm. I was wondering if anyone who has recently received a new Impact M4 .30 700mm Sniper would be willing to verify the twist rate currently shipping with new guns by eyeballing the twist rate data lasered on the side of the liner? A pain, I know, but if someone could positively tell me whether it's 1:40 or 1:22 coming on a new M4 .30 700mm Sniper, I would be very grateful.
Thanks,
Chuck
