Version 2 is a new basic model that incorporates the know-how accumulated through previous M4 variations. The lower frame has been newly designed to match the tough, one-piece molded upper receiver. Enjoy perfect shooting with overwhelming rigidity. The receiver is equipped with the latest System 7TWO bolt, further improving its potential. The bolt release procedure has also been made more realistic. The stock is equipped as standard with a crane-type design, with a waterproof compartment that reproduces its functionality.
