From the manufacturer

While you're upgrading control components on your AR-15, you might as well go big or go home. Literally. This Armaspec AR-15 TCB-31 Tactical Combat Button takes the concept of a mag release and turns it up to 11. Or, more specifically, turns it up to 263. This enhanced mag release provides an incredible 263-percent more activation area, so you can be confident in getting positive engagement on your mag release from any position. Each Armaspec TCB magazine release features an ergonomic design that facilitates easy activation, and the whole of the design is oriented to ensure shooters can activate the release without shifting from a firing grip. The release button fits all 5.56/.22 Mfg: Armaspec
