The GEN 2 version features a polymer lug overmolded onto a precision ground steel rod, and a steel folding charging handle.  The use of a polymer lug means you can now use the handle with an aluminum forend without any wear on the finish. The best part is with the charging handle setup on the Scorpion EVO you can mount the Switchback Charging Handle on your primary charging side and mount your OEM handle on the off side, giving you dual charging ability on the gun. PLEASE NOTE: When removing the OEM or a Manticore charging handle from the scorpion, you will need to depress the detent spring through the lock pin hole to to prevent the spring from being bent, mangled, or damaged. Manticore Arms does not warranty springs damaged from improper removal of the handle. If in doubt on how to remove a handle properly, please email us at info@manticorearms.com
