Ordered and received this upper with bcg within a week. Came well packed in a foam lined box . Mine did shot 55 grain bullets at about a 2.5 in group at 100 yard i kind of guessed that it would with the 1/8 twist. I ordered some horandy match 64 grain ammo and came in at less then a 1 in . Overall i am vary pleased with the upper fit and finish is excellent as i would expect to see from stag . The only thing i would like to have seen was a option to get a different twist rate would like to a twist rate that shot 50 or 55 grain projectiles better as intended this build for groundhogs . I would and will buy from stag again with my next build . Excellent company with great staff.
