A $8 investment that will boost 10-20FPS of your Longshot? I will take it any day.

Using the stock O-ring and just a little bit of teflon tape with this plunger head, it can utilise 80+% of Longshot plunger tube compared to the stock plunger head. With these extra air volume, and coupled with a higher spring load, your longshot will receive a further boost that you always dream of.
