The Battle Arms Development EMMR Enhanced Modular Magazine Release Kit contains the BAD Enhanced Magazine Catch, the BAD EMMR Enhanced Modular Magazine Release and a Magazine Release Spring. The EMMR has a large finger pad to make pressing the mag release easier while keeping a lightweight and low profile design. The EMMR is Precision CNC machined from billet 7075-T6 Aluminum and anodized with a black finish. The Enhanced Magazine Catch has a lightweight fluted design and is made from a single piece of 8620 heat treated steel with a black phosphate finish. The threaded pin is shorter than the Mil-Spec Magazine Catch to reduce the installed magazine button profile.
