Nerf H300 Sniper Riffle

I began construction on this after the nerf gun wars started at work. It was a dark day and I needed some thing more than a mavrick nerf gun. With the awesome power of this gun no one can challenge the H300's range, accuracy and power. With the proper dart the H300 can launch a dart around 300 feet. I am still working on getting it as close to 100% air tight as I can. I am using a bike pump for power and 40 or so pumps is whats required for max distance. I am guessing at 40 pumps the pressure is near 100psi.

You can also load more than one nerf dart into the barrel to make it act as shot gun. The range is diminished but still much further than most other nerf guns. The valve I used is an electronic sprinkler valve and was about $15 making it the single most expensive part of the gun. The reason to go with it over a ball valve or some other type is that it is fast acting. With modification it can be made to actuate even faster but I do not thing that would gain me any thing in the end. Maybe one day I will try it and find out if it does.

Every thing is pvc pipe of two sizes, Two inch and 1/2 inch.
