We recommend using airsoft 40mm multi-purpose shells loaded with CO2 to launch tennis balls. For the stress balls, you can use green gas, propane, HPA, and CO2, as long as you don't overfill the shell with gas. \u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward; it requires removing the font breach screw and replacing it with a longer one. That will be provided in the kit. You will need to align the adapter's mounting hole with the screw hole. This can be a little tricky. We recommend holding it up to a light to see down the barrel and line up. I can send a short video demonstrating the installation.\u003c\/p\u003e\n\u003cp\u003eIn the kit will be the adapter, the longer screw, and a ramrod.\u003c\/p\u003e\n\u003cp\u003eIf you purchase the RB40 MK3 and adapter together, I can install them for you before shipping.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"SizableDesigns","offers":[{"title":"Default Title","offer_id":56440989843622,"sku":null,"price":20.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/4848\/8102\/files\/PXL_20260505_213241979.jpg?v=1778075369","url":"https:\/\/sizabledesigns.myshopify.com\/products\/rb40-mk3-ball-launcher-adapter-40mm-launcher-2-tennis-ball-stress-ball","provider":"SizableDesigns","version":"1.0","type":"link"}
