The Norgon Ambi-Catch is a Commercial Off The Shelf, ambidextrous magazine release. Installation is simple and can be accomplished at the operator level, quickly replacing the issue mag catch.
Ever wonder why your M4/M16 doesn’t have an ambidextrous magazine catch? Well if you are in the Marine Corps it probably does, because in 2007 the USMC issued the Ambi-Catch, NSN 1005-01-537-6498 and authorized units to install it on their M4 and M16 rifles. Likewise if you are a Coalition Soldier. The Canadian C7/C8 rifles have long incorporated the Ambi-Catch and the new Danish M/10 also includes the device. Additionally, select units of the US Army have used the Ambi-Catch to further increase the flexibility of the M16 family of weapons.
One note of caution. The Ambi-Catch works well with military issue Multiple Magazine Holders but is not compatible with the Redi-Mag or Redi-Mod being used by many of you.
