This is my latest pneumatic build.Before building it i made some objectives for this gun:
1.under 2kg
2.be accurant
3.be able to shot more than once with one charge
All come together and here is the final product.basiclly is a coax,when charged up to 100 psi,i can get +3 semi-auto shots .

hey that looks really good man, would like to see some close ups and maybe a video, wouldn't mind making one myself

Nice build! Can you tell more about the valve/operation details?
Some pictures of the valve internals would be good to

Good job!

all information is in my video [youtube] the pic may help too [/youtube]

Very nice looking sniper, and cool way of getting semi. Tho for true semi auto you do need a reload system

Though for true semi auto you do need a reload system

Have you considered using an airsoft hop-up unit as teh loading mech ?? I am sure that at least on of your friends have an old AEG that you can salvage for parts

Nice gun... ohh BTW I really like the video

a reload system?for a coax??no idea how i'm going to put a magazine on the barrel

Well, you'd have to modify the gun a little bit. not that I am saying that there is any need to do so. No one said that you have to build a semiauto gun - I really like it the way it looks right now.

either POLAND has lost his marbles, or JSR has stolen them to use as ammunition....

That bb on your video is not .177, I think you have gotten your information mixed up. ,177 caliber pellets/bbs do not come in white, round or .25 grams. I believe that is a airsoft bb. The blowgun modification is great though, works like a check valve.

Its really not as hard as people make it out to be as long as you're using spherical ammo

Well, if you convert it into an over under gun you can add the hop-up unit. Though, the gun wouldn't look as good as it does now

i like my gun as what it is,would be cool if i get a reload,but i think i won't go change it my original idea was just be able to shot air more than once,doesn't including reload system
here is the gun separated, so it's easier for transporting

it looks really nice! and a very good idea for making it semi, never thought of something like that plug in the blowgun to stop the flow!
pretty cool sniper very authentic look

at what distance did you fire at these apples and what pressure did you use for that?

the distance is about 20m,with 60 psi
Here is a video about how it's made and how it works [youtube][/youtube]
