Spin-Loc® spare tank systems provide customers with the ability to fill the new Spin-Loc® tanks directly from a standard quick disconnect without removal of the air tank from the gun. The lack of need to remove the air tank for recharging has allowed us to also install a pressure guage.

Now shooters can monitor how much air pressure (PSI) is left in the air cylinder during a shooting session.

All this has been done without increasing the original length of the rifle.
