DIY Airgun Out of Blowgun (not PVC)

Hey everybody!!! This is my "airgun" that I built using an old hunting blowgun, black iron pipe and fittings, along with some Shrader and ball valves. This is super fun to shoot and has considerable range and accuracy. I would say its accurate to about 100 yards... if you have a good enough eyeball to predict a 10ft drop. It only cost about $30. Feel free to check out my video here for a better idea of how to build it.

Ok, I'm aware that your blowgun might not be the same size as my blowgun and you might need to get creative to make everything fit properly. The blowgun was just a random blowgun from Cabelas and cost about $15. Overall this project cost about $30.

Parts:

(1) 1/2" black iron end cap

(1) 1/2"x12" black iron nipple

(3) 1/2" elbow

(1) 1/2"x3/8" black iron reducer fitting

(2) 1/2" close nipple

(1) 3/8" ball valve

(1) 3/8"x3" nipple

(1) threaded Schrader valve

(1) blowgun

So the reason I don't have just a straight tube is that it is harder to aim. With a couple of elbows, you can create a riser which enables you to shoulder the airgun and look down the barrel which makes it much easier to aim. The valve is mounted in such a way that you won't jerk the airgun off-aim when you release the air.

Building it is super simple. The hardest part is tapping the hole for the Shrader valve which isn't even necessary. You could get a series of adapters to allow for a threaded. Shrader valve or you could just drill a hole and put one of those rubber Shrader valves in an endcap. It's all up to you. This design allows for a lot of creativity so build it any way you want. Just make sure you use Teflon tape to seal it up.

It is powerful. It dwarfs my old Daisy BB gun in power. It is also very quiet. Definitely able to put food on the table in a pinch. Takes 10-20 seconds to reload and fill with air. Overal it is really fun to shoot and hope you enjoyed this instructable. If it's not too much to ask please vote for the contest that I've entered this instructable in. Thanks.
