Fire Support

The new 5th generation of the Zero trigger again brings a number of changes and improvements. At first glance, a modern shape with bevelled edges is visible. The whole shape was completely redesigned. Only two components are identical to the previous generation. The shape modifications now allow to use in M40 (CM.700) as well as. The upper edge follows the round shape of the bolt housing and fits better on it. The steel and hardened spring guide stopper is now part of the entire trigger. The 5th generation brings back safety lever into the game.  It is now part of the package and you can decide whether to simply screw it on or not. Each piece also has its own serial number.

 

A significant novelty is the adjustable trigger for an ideal position in the bow. The trigger can slide in the groove of the base and is secured with a small allen screw. You can access it even when gun is fully assembled. Smooth adjustment is possible in a 7 mm travel length. Player can set his ideal trigger position.
