Daisy Powerline 7880 880 S 881 Pump Piston Buffer O Ring Gun Bb Air Rifle Part

New pump piston elastomer buffer for a 880/881/880s/7880/822 Daisy Powerline air rifle. This looks like a seal or giant o ring, but its job is to cushion the pump head and it does not help seal the pump tube. This part is a piece of assembly 14 in the 880 diagram and it is located right behind the piston head as labeled in the diagram of the piston assembly. These are tricky to install as they need to be compressed to get the pump head back together, I do sell complete pump piston assemblies.
