Guntec USA AR-15 Extended Mag Release Button Rainbow PVD Coated

The Guntec USA AR-15 Extended Mag Release Button is a lightweight drop-in upgrade for the magazine catch on any AR-pattern lower receiver. Machined from T6 aluminum with knurled grooves cut into the face, the extended paddle sits proud of the receiver and gives your trigger finger a larger, easier-to-find surface for fast, positive magazine changes without breaking your shooting grip or shifting the support hand.

A vibrant Rainbow PVD (Physical Vapor Deposition) coating gives the button a shifting finish that moves through turquoise, pink, and gold tones. PVD is a hard, wear-resistant surface treatment that holds up to regular use, holstering, and the oils on a hand far better than standard anodizing, so the color stays intact long after the novelty finish on cheaper parts has worn flat.

The button is a direct replacement for the factory AR-15 mag catch paddle and installs using the existing magazine catch spring and mounting hardware. It is designed to fit standard AR-15 and AR-308 pattern lower receivers and is a popular add-on for competition rifles, range builds, and anyone who wants quicker reloads with gloves on. Made in the USA by Guntec USA, this extended mag button is a simple, high-visibility upgrade that adds both function and a custom look to your AR lower.
