Left-handed shooters often get the short end of the stick with standard AR-15 controls, but the CMMG Zeroed AR-15 ambidextrous magazine catch kit changes that. This extended mag catch/button kit brings true ambi operation to both sides of your receiver, so you can drop and reload magazines smoothly from either shoulder without fumbling for a control positioned only for right-handers. The extended-release bar gives you significantly more leverage than a standard button, making reloads faster and more intuitive during training or competition.
Installation is straightforward: screw the adapter button into your mag well, then attach the extension to the adapter—no gunsmithing required. The kit uses quality steel construction with a serrated extension surface that gives you solid traction and reliable feedback every time you need to hit the mag release. Whether you're running a mil-spec or aftermarket mag button, this kit works with your existing setup.
Built for AR-15 platforms and finished in matte black, the CMMG Zeroed ambidextrous mag catch is a practical upgrade for any shooter who's tired of compromise controls. Left-handed competitors, defensive shooters transitioning between guns, or anyone who values ambi ergonomics will appreciate the speed and confidence this brings to the firing line or range.
