Guntec AR15 Extended Mag Button Features The Guntec USA AR15 Extended Mag Button is machined from T6 aluminum a material chosen for its strength-to-weight ratio and resistance to wear from repeated use. Knurled grooves are cut into the button s surface to improve grip so the thumb catches the release positively even when hands are wet gloved or moving fast during a reload. The extended design increases the surface area over a standard factory button which cuts down on fumbled or missed presses during competition training or defensive use. This is a straightforward drop-in part that upgrades one of the most frequently used controls on an AR-platform rifle. The standout feature of this button is its Rainbow PVD coated finish a matte multi-color physical vapor deposition coating that resists scratching and fading far better than paint or anodizing alone. Because the part is lightweight it adds no meaningful weight to the lower receiver while still delivering a noticeably upgraded look and feel compared to the stock button. Being made in the USA it is built to the fit and finish standards AR-15 owners expect from a precision aftermarket control. Shooters looking to combine faster more reliable magazine changes with a unique splash of color on their build will find this button a simple and effective addition.
