Hey guys just purchased my first savage rifle. It is a mark 2 TR 22LR. I am very impressed with the rifle in general but there is one thing that seems odd. At the mouth of the barrel where the cartridge is chambered there is a small lip all the way around. U have to look very close to see it and u can feel it with a fingertip. Is this normal? The gun seems to shoot very well. Havent tried any groups yet so I dont know how consistent it will shoot. Should I send it in? Thanks guys.
