Built to the same degree as our other CMMG ZEROED charging handles, the CMMG ZEROED .22 LR ambidextrous charging handle was designed specifically for our .22 LR Conversions as well as our dedicated .22 LR Uppers/Bolts. The ZEROED .22LR charging handle features a filled-in, reinforced channel in the charging handle to prevent instances where .22 casings can eject into the open channel of a standard charging handle.
