This was my first pneumatic. Ive got muzzleloader sights on it and its very accurite with the 3/4" barrel. At 120 psi I can put a hole through a hairspray can 50 feet away. I also have a 1/2" barrel for .44 caliber pistol bullets. They do a lot of damage. I havent chronographed it but its probably g...

I had been trying to buy some 1.5" sdr 21 pipe but no hardware stores around here even know what im talking about

Actually i tried it and it is more powerful than my 3/4" modded sprinkler valve. Its not quite as cool but i believe im shooting whole potatoes about 200-300 yards. I will look into the pistons though but im out of money

U need a sprinkler valve and blowgun. That makes a huge difference. very fun!

Sry, im an idiot but computer didnt load everything. Now i see what u mean

I dont see how a modded blowgun can allow more airflow than a sprinkler valve. The opening on a blowgun isnt but like 1/4". you can get a 1" sprinkler valve and mod it.

My first pneumatic used a jartop 1" sprinkler valve modded. It was impressive but i want more airflow. Im now making another one with a 2" ball valve so i can get more airflow. The only thing is that manually opening one of these things is hard to do fast. Has anyone ever tried attaching a spring an...

Is that drain pipe or something? And also nobody answered what size tennis ball barrels are.

Does anybody know what diameter pvc can be used to shoot golf balls and i think 2.5" ID shoots tennis balls but not sure?
