That's NICE

Beware of the 1/7 twist barrel. Unless you plan on shooting high dollar ammo, like 65-77 grain rounds it is said that twist rate will not stabilize the lighter 55grn rounds enough to make nice groups. All I have is 1/8 on a LaRue 20" upper and 1/9 on all my others. There is a thread or two going now about accuracy questions on a 1/7 barrel and everyone has suggested to use heavier rounds to get better groups. 5.56 ammo is already pricey enough without having to buy premium or match ammo. If you want a paper puncher I think the 1/8 twist or 1/9 would be better suited for a range toy or match gun. If you want a single hole punch then the 1/7 would be ideal.
