yup very surprised to see that as well. youd think they would at least use a 1:7 twist for being what it is. still a bad ass gun on MW2 though.
Another mark in the history of arms manufacturers limiting the "militant application" of military-style arms.
They won't give you a 1:9, because they don't want you to be able to handle larger bullets, they want to use as few Mil-spec parts as they have to, because that's what the military gets...and we wouldn't want civilians to have the same capabilities as the military, WOULD WE?
We need more armorers out there to be willing to lend some combat and defensive arms capabilities to regular people.
