Well spudfiles, I've been quite busy with this project for the past few weeks.

SPECS:

Valve: 1/4'' QEV from ebay piloted by a 1/4'' slide valve also from ebay.
Chamber: 1/4''x6'' steel pipe nipple
Barrel: 30'' Brass tight bore Airsoft barrel cased in 1/2 PVC
Operating pressure: 25-450psi (so far)
Air source: remote (backpack ) Paintball HPA tank and regulator.
Magazine: 12 round, spring loaded, non-removable magazine.
(the magazine is non removable, and is loaded by sliding the follower all the way down, where it locks, and then loading through a port in the side of the mag.)
Scope: I bought the scope today at meijer, 8 dollars for a 14x zoom cross haired Tasco scope....

This gun is true semi-auto, and fires with each pull of the trigger.
I cannot pull the trigger faster than it will shoot.

The stock was made from a 2x6, and took aprox... 4 hours.

This gun will happily punch through the bottom of a pop can at as low as 50 psi. At 450 psi a 20g king Armour BB chips my sidewalk.

I hope to take a damage video soon.

Video was taken at 250psi. (not Airsoft war safe.)
This different sounds in the video are caused by a few doubble feeds.

My detent seems to be a little lose. hahah.... also about halfway through shooting... i ran out of ammo(12 rounds), and after that was loading them 1 at a time into the clip.

For now i use the slide valve.

The trigger is a W.I.P

Also, i do have another barrel/breech assembly for it... made of copper.... just the right size for AA Batteries 8)

Damage photo... semi auto fire... 2 clips at a pop can from about 25 feet.
300 psi :twisted:

As soon as i can take one. Yes. For sure.

I have a few different muzzle breaks... that drastically change the sound... i will be sure to get those in the video as well.

For now... more pop carnage.

Just a clip load in a pop can from about 25 feet at 100 psi this time.

Yes, that QEV, Only, i bought a lot of 7.... for $40usd.

I pushed one to its limits...... well... i tried to... but i refused to fail even at 700 psi... and i did not want to go any higher.

EDIT

haha. :shock:

Yes, i used to be a noob. I have learned alot though, and now realize the limitations of my cannons.

This particular cannon would never even shoot close to that kind of range.... simply because of the tiny, light projectile, and the low amount of energy involved.

Any ways, back on topic... what do you think of the stock? i am particularity proud of that stock... hard to tell in the photos... but it is very rounded.... and looks pretty darn good if i say so myself.

Yeah, I forgot to say... The stock looks REALLY cool. It's very original and almost futuristic looking (being so curvy I guess)... Great job :wink: 8) :D

Nicely done! And using off-the-shelf parts, well made :)

One small thing, does it have an integral suppressor or did you just reinforce the barrel? Sounds pretty loud in the video.
