I was looking at aftermarket barrels and saw these two options. I was wondering if anyone could help me out by telling me what the diffenrence is of them.

You must be looking at Savage barrels. The shank size depends on your receiver. WSM's, RUM's, and Target actions are large shank while the others are small shank. They are not interchangeable.

small shank - 1.055"
large shank - 1.120"
