Building a reliable .45 ACP AR when using Foxtrot Mike Products. The FM Products FM45 .45 ACP lower receiver is machined from a block of billet 7075-T6 aluminum and is compatible with Mil-Spec components. This dedicated .45 ACP AR lower is designed to be used with the highly popular Glock magazines and even features a last round bolt hold open which is not a common feature of other .45 ACP lowers. The AR .45 ACP lower Glock compatible receiver comes stripped, so you can customize it to your liking. It does, however, come with the proprietary magazine release and bolt release pre-installed. Start your AR-45 build off right with the FM Products .45 ACP stripped lower receiver.
