Pump Aid - Daisy Powerline 880

This will save your knuckles from banging on everyone's favorite backyard plinker. There are three tits that you can sand if your lever is thick. Add tape if the lever is thin - wrap the tape around the section that slips into the slot. The part shown on rifle is a quick print with only two top, bottom layers and two shells. Thus, it has some gaps but using three layers will seal them up nicely as shown in another photo.
