The new generation of complete bolt from APS for the latest APS CAM870 MKII series of shotguns, which can also be fitted to older versions of APS shotguns. The AMS CAM870 MKII series metal bolt for shotgun replaces the older version of the first generation shotgun from APS. This new type of bolt, thanks to its simplicity and reliability, has become the standard for all currently produced APS shotguns, replacing the first boltversion that used gas-filled shell cartridges. Thanks to this new type of bolt, you will no longer have to fill the gas into individual shells, but you can store it in metal bolt. Together with it you can use the latest type of shotgun shells from APS. The replacement of the bolt is quite simple, but we recommend that it be entrusted to our specialist service.
