I am about to install one of these in my Beeman R10 rifle. If you look carefully, you will see that the seal is NOT symetrical. One side is rounded, the other has a "step" on the inside and outside. Which way does the seal go into the breech? Thanks for any help you can give. Pete H
I have an old Beeman HW50s with the leather breech seal; will this safely replace it?
Do you have the specs on this part?
Would this seal fit a Gamo Big Cat? Looks the same!
No it would not. You need Piston Seal, Fits Gamo Whisper....
