Even though it's my bread and butter, my personal airsoft gun collection has never been extensive. I recently found an old (probably made in the early 2000s) Tokyo Marui MP5SD6 however, and to scratch an itch turned it into a 30 round per second CQB machine, complete with the latest in bluetooth-con...

Fuck off, spamcunt.

I posted some time ago showcasing a high pressure 'Toolie' style valve I built out of stainless steel. This is the progression of that project. I'm sorry for making a new post, but I figured it'd be easier than modifying my old one. Feel free to move this if needed. shown below is the valve assembly...

Hey guys currently I have a smei auto airgun operating on 200psi with a 3way 2 position valve, qev and dump chamber with a electric solenoid to chamber rounds. currently im using an esp32 to time the valve on and off for 10-20 milliseconds. For some reason i can get the valve to turn on and off quic...

One of the experiments I've done with this project to to see how burst disk strength influences performance. Intuitively one would tend to think that the stronger the disk, the higher the pressure it will burst at and therefore the better the performance will be; this might be true of a pneumatic bu...

It's been over a decade since I first made this project and almost as long since I dabbled in hybrids so here is a recent project along the same lines: 20231108_233649.jpg Nothing particularly special about the design, chamber volume is around 34cc and it's currently fitted with a 490mm long 6mm bar...

I made a 0.177" barrel attachment for this thing, at a 20x mix it was pushing 0.35 gram BBs to just over 1800 feet per second :D that's 39 ft lbs of energy! https://www.youtube.com/watch?v=23-DWhJ0-MA The same barrel hooked up directly to the air cartridge at 2500 psi yielded 1143 fps, still impress...

On Suckering In a New Generation of Spudders Yes... I realize it's a completely hilarious/original way to phrase it. Rather than an introduction establishing that I don't think new spudders need to be suckered in, along with other wordy creations, it would be much better to just dive in, givin the ...

I made a tennis ball cannon using a 3” sprinkler valve. It fires a ball at ~150 yards at just 30 PSI. The valve is manufactured by Dorot, repackaged by Galcon, and sold by Drip Depot. The stated flow rate is 390 gallons/minute which is 10x the flow rate of an average 1” sprinkler valve. The valve is...

Salut à tous je suis français et je vous présente mon fusil hybride blue king✌️ Très peu de français se lancent dans de tel projet j'ai l'impression... Quelques données techniques : mix 11 butane, disque de rupture en aluminium de 0.2 mm d'épaisseur Chambre de 182 cm3 et canon de 17.4 mm x 100 cm! É...

Hello guys. I just wanted to share with you my first prototype for my spud gun and also share my ideas. I made a prototype for my first spud gun but the ammunition is a nail dart instead of a potato. The barrel is about 3ft (approx.) and the diameter is 1/2 inch and it is a blue pvc. The combustion ...

Since we're talking about rifling, have you seen how people are using "electrochemical machining" to rifle barrels from steel tubing? A very interesting way of doing it for those who are more at ease with 3D printing although I suspect it would be a challenge for rifle length barrels. mark.s has a ...
