I am currently having a 308 built by Collier Rifles in Millen,Ga. They have a Kreiger in stock that is a 1:12 twist, or they can order a Bartlein 1:11.25. They have a rifle with that Bartlein in a Accuracy Int stock and it shoots light out. Its gonna be a 20" suppressed rifle, is one better than the other? also the kreiger is $100 cheaper. thanks for any advice or input.
