This is my first eh r rifle lol and my handguard screws were lose and my gas block canted to one side. I slid my gas block forward and used a pencil to make a line on top of barrel in line with the gas hole in the barrel and I think mind is almost spot on. Once I fire it I will quickly know but I’m a newb when it comes to eh r’s. I know every other style of firearm but I always avoided these cuz of restricted class. So far it’s one sweet rifle
