The Next Level Armament NLX556 AR-15 Ambi Charging Handle-Economy is a charging handle that is very similar to our original NLX556 Charging Handle with a new "ear" design. Still manufactured with 7075 aluminum, we were able to make some small tweaks to the "ears" while keeping the aggressive feel. These minor changes made it possible to bring this charging handle to market at a lower cost. Mfg: Next Level Armament
