semi-auto bb gun!!

[soka]

Hello, i made a semi auto bb gun, Jules 56 has inspired me with his system :

We can make great things using the pressure of the chamber instead of trying to make a gbb which is much more complicated.



Have a nice day!!

A little bit crude but very ingenious, I like!

What pressure are you running at and what's the power like?

[soka]

3 bar, and the bb go as far as a 1 joule bb gun . I think i can go up to 5bars with my crapy piston but i dont have compressor, i only got a shock pump which is very howfull to pump my extinguisher!

Take this gun as a prototype , i will ameliorate it!

So the qev piston is attached to the rod that recocks it... how does the piston attach to the rod?

Thanks for posting on this forum.

Edit oh wait i get it now the pilot side is attached to another piston and when it pilots the spring pushes it back. Sick. I'm totally gonna use that.

but very ingenious

dude, it is an air cylinder

@soka
heh ignore what I wrote above it's a personal revenge I've got a gun that uses the same loading mechanism
Good work

ohh btw, have you considered building a fridge compressor ?

[soka]

I would like to find a fridge compressor, i am thinking of it everydays.
but its a little hard to find in france.
I will post other movies and damage etc....

Never said it's bad idea, just too complex for my liking - not something I'd bother with myself, but it's pleasant to watch the results of those who have gone through the effort

[soka]

hello , i have found some good piece of alu to make a stock and something to hide the plumbery stuff.
And i made an other verin more resistant to pressure, i can go to 10 bars easyly.







sory for the pictures , iwill post others better.

[soka]

So better pictures for you !
Soon i will put the scope on, it will have a terrible look!!

I think you mean "good" look. The french tend to use the word "terrible" in a good sense, no? Like, "pas terrible", that isn't a bad thing, right?
Anyway, this gun needs a good coat of paint and then it will look awsome! Good job dude
