An Elaborate Explanation of the Air Restriction Mechanism Inside a Nerf Blaster

The “Engineer Guy” Bill Hammack breaks down the design of the air restriction mechanism inside a Nerf N-Strike Elite Triad EX-3 Blaster that limits the toy to only firing one dart at a time regardless of which of the three barrels are loaded.

Hammack’s associate Steve Kranz gives a similar explanation of the Triad as well as examining the mechanism in the Nerf Zombie Strike Doublestrike Blaster in a separate video.
