Next Level Armament AR10/AR15 Extended Magazine Release Button Anodized Black. Slightly extended over mil-spec for reliable activation and cleaner mag drops without catching your gear. Machined each extended magazine release button from 7075 Billet Aluminum and finish with hard coat anodizing. The longer overall length allows easier magazine exchanges and the extra diamond machining provides maximum grip. The release button fits both AR10/AR15 Platforms. It does everything you want a magazine release button to do but better. The release button installs like the standard mil-spec release. We extended the length from .3in to .4in enough to enhance performance while keeping a low enough profile to avoid snagging on slings and equipment. Not only will this increase consistency and performance but the closed diamond patterned end also makes your rifle look great. Whether you shoot for fun or competition our release button will help take your rifle to the Next Level.
