Nice reproduction on the buffalo bullets. They've all ways worked well for us...

The link is lost but I presume you're talking about the spyra water gun with that big Kickstarter campaign. I would look at a water pump like this 12volt RV water pump with a built in 80psi cut off https://www.amazon.com/dp/B074MZYS37/ref=cm_sw_r_apan_glt_fabc_MK5936AWFRVX9PYWN9DA?_encoding=UTF8&psc...

Looks good. Are you going to make one for testing?

Sounds like an interesting idea, I think an adjustable chamber to barrel spacer would be great.

Also clamp on ergonomic grips for blowguns and control values

That's an interesting use of an air cylinder, but you really have the same effect from a QEV or a more common homemade piston valve. And as long as the air cylinder internal diameter is greater than the barrel diameter it should work fine. But I don't really see an advantage to using an air cylinder...

Latest electro-pneumatic with automated velocity control and laser range finder. Air burst system optional. FCU has electronic pressure sensor, firing, round charging and programming based on LRF data.

Image of airburst was a round fired at 400fps 150ft from target.

You need to shut off the air feed or the recharge rate will effect the projectile velocity as the tank discharges. This varies on factors like ballast size and operating pressure. Smaller ballast needs higher psi but gets more efficient as you go. 800psi can be used in quite a small ballast and prop...

There is a downloadable PDF for it

Hi, Ive had this design, in my head for at least a year now, and Ive finally found the parts I need for it. I would be very grateful for any comments on how I can improve it. The Expansion chamber will be made of 5 mm thick PVC that has two seals on the outer rim of the PVC piston. Almost all the in...

Hi, I’m not sure if you are still monitoring this post, those red finned projectiles are awesome, where did you get the file from please. Did you print the launcher yourself and the same for that did you download the files for that.
Kind Rgds

Here is an interesting design we came up with. Its a cross between a shotgun look and grenade launcher. I added a homemade stock to the rear and sprayed the barrel black as well. We call it "The B*tch"!

Here is the demo video:

also i hope you have a great day

i think a small bead seater whould be good for the chamber with 2 in pvc and bolt system using a male slip femal union and a male slip adapter on that i actually got akess to a 40 mm he grenade and rapped in duck tape and shot it out that was my prototype

i am next working on a semi auto gun next that also shoot 40mm
