China Lake grenade launcher

The China Lake pump-action grenade launcher or NATIC is a pump-action grenade launcher that was developed by the Special Projects Division of the Naval Air Weapons Station China Lake, which provided equipment to United States Navy SEALs. == History == The M79 and XM148 grenade launchers were single-shot, and the repeating T148E1 grenade launcher was unreliable, so a request was made to China Lake engineers.
