The AES Weapon Shock Simulator (WSS) is a nifty device that simulates the shock environment created by firing an M4 Carbine. The simulator is designed to test the effect of firing on picatinny mounted accessories such as scopes and lights. The high-speed video below shows how the force generated by the WSS compares with forced generated by an M4. I am impressed that even belt bounce is accurately reproduced.
