Plans for homemade airrifle

[jaffe]

I'm planning to build a simple air rifle that looks like a M4 with grenade launcher, the M4 shoot bolt action the grenade launcher is powerd in combustion. The problem is the loading from the gun, i think that is I yuse a spring powerd magazine the bb are pushed to hard in the barrel and wonth shoot out the barrel. Dus somewhone no what I can do on this problem or wil it yust work .

Maybe a sleve that acts as a bolt inside/outside the barrel that would seperate the chambered round from the spring tension applied from the magazine?

You could make a BBMG with a relatively small chamber, by using brief trigger pressure you can fire in short powerful bursts, without the need for a complicated magazine setup - I used this technique with my Standalone Vortex Project, as you can see in this video:

What are you planning on using for an air source? If you're going for multiple shots, your best bet would be a high pressure air or CO2 bottle regulated to lower pressure.

@Integral
I don't understandt what you mean(stupid dutch people ) If you could draw a schematic from the loading system I will understand it(maybe ).
The air source is from a plunger(bolt action), the trigger is yust a simple washer .

Ah, do you mean that the rifle component is shot using a spring powered piston, not by compressed air for a reservoir?

[jaffe]

Yes.........................................

Ofcoarse I want to make a gun on compressed air, the problem is yust that I don't can make a valve that don't spill all the compressed air from the tank. And also I like triggers .

In that case, I think you will find this link very useful Ignore the complication of having the ammunition in separate cartridges, you could have the BBs feeding directly to the breech.

[jaffe]

How do you mean directly to the breach?(yeah I'm stupid )

I think that a hammer valve can be possible to make(a kind of).

[jackssmirkingrevenge]

I mean the BBs are fed into a T with a spring, I'd love to be able to draw a diagram but my resources are a bit limited right now.

An easy way of making a hammer valve is taking a normal blowgun, removing the trigger then making a spring loaded hammer to strike it open - with a bit on ingenuity you can lift a hammer mechanism from a toy gun made for exploding caps.

[jaffe]

The problem is that in this stupid country they don't sell blowguns valve's. I have tried to make a simple valve but it didn't work so now I'm drawing a kind of paintball gun valve, but I'm stuck by the problem that I want to make it automatic

I find it hard to believe that no one in Holland sells blowguns - have you been to a hardware shop that sells air compressors and accesories?

[spanerman]

im pretty sure ive seen a blowgun on one of BtB's guns and hes dutch aswell! drop him a PM and ask..
