FX Dynamic DoubleAir Adapter Kit allows the addition of a 300cc carbon fiber bottle to the rear stock, allowing a higher shot count. For the most air possible, use this adapter kit to move the existing front 300cc bottle to the back, then put a 480cc or 580cc bottle at the front. (A setup with a 300cc and 580cc bottle would yeild approximately the following shots per fill: .177-293 / .22-176 / .25-132 / .30-102)
- Kit includes 2 adapter pieces
- Fits only on the FX Dynamic Block (currently the only rifles with this block are the FX Panthera and the FX Panther Hunter Compact)
