I finally have this product in stock.  Looking for a better pump cup for your Benjamin 310, 312, 317, 710, 720 & early 340, 342, 347 rifle?  Well here it is. This pump cup will out last the existing pump cup that is currently available.  The cups with the hole in the center will usually last for about 4 to 5 years? This new design will probably be the last pump cup your Benjamin rifle will ever need. Also this pump cup head is an upgrade version of the pump cup heads that were made between 1950-1953. So this is a direct replacement. Made with 85 A shore hardness Viton rubber.   New pump cup will allow you to get more air pumped in in shorter time. Will fit Benjamin rifles made between 1939-1985ish? This sale is for 1 pump cup head only.  Any questions about this new product please contact me.

  I do combine shipping if multiple items are bought.
