Not sure what you are putting this on, but when I hear up to 100 yards, I immediately think dot sight or low power fixed scope. Maybe one of the small diameter dot sight would look and handle right on your rifle.

100 max = 1x or 2x
150 max = 2x - 4x

Just my opinion. I have made lots of 0 - 350 yard shots with a Weaver(1960's era) 4x scope. I made those shots in the 90's.. Dad's rifle. I never felt cheated, but it was all I knew at the time.
