I just had my FFL order a 20 inch SS A4 upper for me. I wanted the 1/8 twist and I was going to go with the NM upper but I don't need the comp FF tube. I thought the two uppers were the same with the exception of the front sight and FF tube. I just left your websight and I see the twist are different on the two rifles. I have to have at least a 1/8 twist. Can you confirm if a standard upper with the SS barrel is a 1/9? Can I have it changed to a 1/8? Thanks!!!!!



I think I read it wrong after being up for 20 hours (working 2nd job trying to pay for the upper)....From the looks of the websight the 1/9 is for the CM barrel and the 1/8 is for the SS.

Correct....all of the stainless bbls are 1:8, except for the optional 1:12 in a 24" varmint bbl.
