The 5.7×28 cartridge is becoming popular for its flat trajectory and manageable recoil, making it suitable for target shooting and potentially home defense – although Ohio laws should always be followed. The Banshee 200 platform offers a different experience than traditional AR-15 builds and can be a fun project for experienced AR builders.
