Armaspec ECB Slant Magazine Release Button

The Armaspec ECB Slant Magazine Release Button, Black (brand part no. ARM205-BLK) is an ergonomic upgrade for the magazine release button on a standard mil-spec AR-15 lower receiver. Armaspec angled the Slant button to match the natural angle of a shooter’s index finger as it reaches for the release, rather than the flat, straight-on button found on a factory lower. It keeps the same footprint as a standard OEM magazine release button, so it drops in without any fitting, while creating a more comfortable, natural motion during a magazine change. For shooters who run a lot of reload drills, that small ergonomic difference can add up over time.
