HISTORICAL SUMMARY OF ACTIVITIES:
1JUL64 - 30JUN65 - Detachable Grenade Launcher for Rifles - A launcher adaptor was fabricated and assembled to a single-shot 40mm grenade launcher. The 40mm grenade launcher was tested on the M14 rifle. The results of test firing indicated that unless changes to the M14 stock are permitted in order to bring the launcher closer to the magazine, this system will be awkward for handling and aiming. The trigger position must be redesigned to enable the shooter to grip the stock and trigger on the launcher at the same time."

Notes: Has 40mm grenade launcher (40mm X-1) attached underneath barrel.
