Strike Industries ARMMR Modular Magazine Release - Black Steel w/ Polymer Button - AR-Platform

The Strike Industries ARMMR Modular Magazine Release is a drop-in upgrade for mil-spec AR-15 lower receivers. The magazine catch is machined from steel with a black finish, paired with a lightweight polymer paddle button and a SUS630 stainless steel shaft sleeve and button adapter for durable, corrosion-resistant service.

The modular design lets the shooter swap button profiles without permanent modification to the lower receiver. The package includes both a standard and an oversized polymer button, giving the user a choice of paddle reach and surface area to match their preferred shooting style. The release installs as a direct drop-in replacement for the factory AR-Platform magazine catch.

Built for the AR-Platform, the ARMMR delivers a clean, reliable magazine release with the modularity to suit a wide range of AR-15 builds.
