Try a Leupold Ultralight 3-9 X 33. It's 10.96 inches long. Another option is a Nikon SlugHunter 3-9 X 40 with BDC. It's 11.3 inches. Another is a Weaver Classic V7 in 2.5-7 X32. It's 11.5 inches. Obviously, you've got several choices depending on what you are specifically seeking and how much you wish to spend. Good luck.
