I have one of those :) and it has its own hammer, so you can use it to shoot (low powered, hopelessly inaccurate since there is no barrel) BBs with your thumb :D

wow that is pretty damn cool> I would make a barrel and stock for it. Where did u buy this and how much would if cost in euros? Oh yeah and how many shots do u get on one capsule? thnx

I don't need to, because it came with a rifle :wink: I think I paid around 350 euros for it.

Purchased from my local arms merchant, and one capsule gives you around 2 magazines (around 40 shots) at around 450 fps with steel BBs.

Too these things arent legal here:( That thing looks awesome! and 450fps with steel bbs damn, it prob has 3-4joules of muzzle energy.

It's enough to penetrate a soup tin at 10 metres. That said, it has a smoothbore barrel so accuracy is questionable at best. What I do like about it most is that apart from obvious firearm related components (barrel, bolt, gas tube etc.) a lot of it is genuine AK parts - it's apparently made in the same factory as the powder-burning original - so it feels very real in your hands. Cocking the bolt handle for example doesn't do anything for the function of the magazine, but it sounds cool :D

If you have 300 quid to spare and have an understanding aquaintance over 18 years old, you could have one ;)

Its like this topic discussion had died... after reading everything is still question: How does the valve(part 4 of the mag diagram) after being pushed, release compressed co2 from its chamber to the part that pushes the bb? BTW im sort of inexperienced when it comes to complex valves and circuit designs like a solenoid. What are these parts to the drozd and how do they work?

What I meant was, don't post in old threads. Most members don't like that unless you have something important to add.

I'm glad someone bumped this thread, because I'm looking for an extremely compact and light semiautomatic BB gun to use in a robotic aircraft that I'm building.

So, if I buy the magazine with valve and co2 adapter and add my own barrel, could I build it into my airframe and control it electronically?

I've been at this a LONG time, and I'm open for alternate suggestions.

My main batteries weigh around 1500g and offer 16A/H at 14.8volts.
I don't have a lot of extra room or payload capacity so if you can think of an electronic, semi/fully automatic gun that takes 12g CO2 cartidges, please let me know. I'm hoping for the complete gun system to weigh around 500 grams.

Do you know where I might buy the drozd magazine or something like it?

Thanks,
Matt

I remember this: http://www.spudfiles.com/forums/who-has ... 19506.html

Still looking eh?

I would repeat this suggestion of making a BBMG with the fuselage structure as a pressure chamber:

Image

The twin booms are principally composed of two 2 or 3 litre soda bottles which are also the air tanks, filled to 150 psi or so. This should give you at least 10 or so seconds of firing time on full auto

In a central nacelle there is the valve mechanism, BB chamber, barrel and camera facing forward, as well as batteries, RC gear and a motor driving a pusher propellor.

If you want semi auto, servo triggering would give you some interesting opportunities - but shooting from the air I would surmise that you need full auto to actually have any hope of hitting something smaller than a barn door.

A cheap AEG airsoft gun will do, don´t know if that power will work for you through.

Now, BTW, did anybody every made a functional copy of a drozd? Because I couldn´t do it and I´m planing on buying a stronger solenoid and try again.
