I have up for sale a ready to go package of Thunder B's It comes with 3 cores. One is brand new and still sealed in its package. Two are working though one may be close to going. The 10x shells are Soundflash style. 15 new cartridges of co2 made by Crosman still in the box. I am asking $55 shipped Conus I am shipping UPS ground because of the co2 cartridges. I can also sell parts individually so make me an offer! Check out my other post for good deals and other items that may interest you!
