The 5.7x28mm cartridge was designed to provide rifle caliber-like ballistics with less recoil than most pistol caliber carbines. If you like the modularity potential of the AR15 platform you’re in luck this BANSHEE is built on our Mk4 AR15 platform which uses a standard AR15 lower receiver and our new and improved 5.7x28mm AR conversion mags which means no need for a proprietary lower.
