Airsoftjunkiez announced tha they have in stock the Silent Industries MTW CNC Bolt Catch. This is CNC machined from high-grade aluminium ensuring that this bolt catch will never snap. It sports a matte black hard coating which is the same color as the body of the MTW and its sporty design fits the style of the MTW.
Brian Holt of Team Blacksheep lists the five reasons why the M4 Bolt Catch in airsoft fails... "The “functional bolt catch” for the Airsoft M4 rifles can be a nice touch for the detail but it is more of a gimmick and will lead to failure and here are the reasons why."
