The Rock Rose airsoft channel goes over the Escort ES simulator Stun Grenade made for airsoft use. This has a realistic look with full metal construction. Since this is a "Stun" grenade it is an airsoft sound grenade that has an output of 130 decibels... "Tsumugi introduces the ES simulator stun grenade released by Escort."

A tuned up SHOEI MG42 done by Escort Project, who are cooperating with SHOEI is now on YouTube. The muzzle velocity shows an average of 90.8 metres per second or roughly 321.5 feet per second. The vibration shows an amazing rat of fire which the shooter should be able to make the airsoft machine gun steady to properly shoot at targets. 0.20g BBs are used in the test.
