== Principal marker families ==

=== J2 ===

The '''J2''' was one of CCM's first complete marker platforms.

It was produced as both a mechanical semi-automatic and pump-action marker using a CCM-manufactured receiver.

The J2 was compatible with Autococker-style barrels and numerous internal components.

Its construction included a custom-machined aluminium body, adjustable trigger frame, removable barrel and distinctive rear body milling.

The pump configuration used a guide-rod assembly and could be converted to semi-automatic operation by replacing the pump mechanism with an appropriate pneumatic front block.[2]

=== Series 5 ===

The '''Series 5''' was an Autococker-compatible marker platform offered in mechanical semi-automatic and pump-action configurations.

VintageRex records both the standard Series 5 and a right-feed pump version designated '''Series 5 RF'''.[3][8]

The platform used a stacked-tube arrangement with a hammer, sear, valve and mechanically operated bolt.

CCM's technical documentation describes the Series 5 alongside the Series 6, reflecting their related operating principles and component arrangements.[6]

=== SS25 ===

The '''SS25''' was a compact pump-action marker using a Sheridan-style valve system.

VintageRex documents the marker with direct feed, a removable barrel and constant-air operation.[3]

The SS25 shared operating principles with CCM's Series 6 prototype.

Its manual documents a mechanical auto-trigger system allowing the marker to fire when the pump returned to its forward position while the trigger was held.[9]

=== Series 6 ===

The '''Series 6''' was a dedicated pump-action marker catalogued by VintageRex as a 2006 model.

It retained the mechanically operated stacked-tube system used by CCM's earlier pump markers.

Its construction included a separate pump assembly, removable barrel, adjustable trigger and externally accessible components for maintenance and adjustment.

The Series 6 was produced in different configurations, including versions using alternative pump handles, grip frames and feeding arrangements.[3][6]

=== Series 6.5 ===

The '''Series 6.5''' was a further development of the Series 6 family.

VintageRex lists the model with a 2006 catalogue year and identifies it as a .68-calibre pump-action marker.[3]

CCM's technical support archive includes separate material for the Series 6.5, reflecting differences in its construction and maintenance procedures from earlier Series 6 models.[6]

=== T2 ===

The '''T2''' was a .68-calibre pump-action marker using a half-block receiver arrangement.

Unlike a conventional full-block Autococker body, the half-block configuration reduced the rear portion of the upper receiver and used a corresponding bolt and cocking arrangement.

The T2 retained a manually operated pump system with a mechanical auto-trigger.

Its operation followed the same general principles as CCM's earlier Series 5 and Series 6 markers.

A technical manual produced by the Pumpenstein community documents the T2's pump mechanism, trigger system, regulator and internal components.[10]

CCM's official website also identifies the T2 as a pump marker.[7]
