The Wolverine MTW M4 mag is your best companion with your Wolverine MTW. This mag works with the MTW's empty mag detection using a small lever on the top-back of the mag. When the follower is done feeding every shot, this lever will engage with the MTW's empty mag detection system and the gun will stop firing. To resume shooting, put a fresh mag in and hit the bolt catch.
(Note, This mag may not work for any other airsoft replica's empty mag detection system. Please use the proper mags with the proper system)
