I Purchased a set of these about 2 years ago so that I could mount a scope on my Benjamin 397PA .177 air rifle. To use a standard eyerelief
scope the rear sight should be removed. Mounting this base was simple and solid. It has worked very well for me aiding my weakening eyesight. Also these fit the older Sheridan Blue Streak air rifles.
