Thought the weapons section could use something new.
The China Lake is a Pump action 40mm Grenade launcher based on the classic M79 Grenade launcher.
Named for the China Lake Naval research station where it was developed. it saw use with the Navy seals and US Army Special Forces in Vietnam.
Boasting a four round capacity three in the tube one in the chamber it offered a faster rate of fire ,higher ammo capacity and a faster reload than it's M79 counterpart. Still it was eventually phased out in favor of under slung grenade launcher like the M203 and fewer than 100 were made.
Still it's a pump action shotgun on Steroids and a pretty kickass weapon.
