These are just the regulators for the tanks. Some of these are appropriate for the tank that is on your airgun. Others are designed specifically for use on a fill tank. Please reach out to us to help get the right regulator for you.
Please note that proper installation of these products is VERY important. If you have ANY reservations about installing these, or don't know the proper procedure for removal and installation of a tank regulator, please reach out to us for installation services, or take it to a qualified business to help you with installation.
