A quick demo by Frog Engineering of their custom-modified airsoft gun. A hobbyist dressed in full tactical gear, complete with a helmet and eye protection, holds the Tokyo Marui MP7A1 submachine gun variant in a wooded setting.

The demonstration kicks off with the user inserting a magazine and racking the bolt to prepare the airsoft gun for firing. He then switches the selector switch, raises the replica to his shoulder, and lets loose a brisk burst of semi-automatic shots, followed immediately by a rapid spray in full-automatic mode. The rapid firing sounds a bit like an angry mechanical cricket, echoing briefly through the quiet forest.

After emptying the magazine, the user quickly removes it to show that the session is over. He wraps up the short clip by turning back toward the camera and giving a cheerful thumbs-up, signaling that the custom build is functioning as intended.
