I have a Model 1 762X39 upper with a 20 in barrel. I love it and use it for hog hunting. It will easily shoot 1.5" or less groups at 100 yards with it's favorite ammo (Barnal).

Mine has the target crown on the barrel as I prefer no muzzle attachments on my hunting guns.

Great upper, I have had it for years and enjoy it every time I shoot it.
