6mm semi - added trigger & mag!

Not sure if I understand the question, when it comes to pop-offs though I believe I've done my research

in other words... whatever you want to build jsr has probably already tested it (and the prototype exploded)

in your movie the magazine is above the barrel, could you use this system to feed ammo into the gun like in a m-16 or AR-15 setup?
also, how did you make the piston? I tried to cast a piston sorta like that one once out of hot glue, it stuck so badly that I couldn't get it out with a hammer.

Did you lube the tube before you poured the glue? That helps a bunch with removal. To make the mag feed from the bottom he could simply add a spring... doesn't take a rocket scientist to figure that out dude.

[gluegunner]

actually I was more wondering if he had done it.

[jackssmirkingrevenge]

I gave it a go here but was let down by a faulty seal.

if you can upgrade the materials to tuffer things you could use a stronger spring for a faster return. then pulse the air to it for full auto.

Managing to do this successfully was my holy grail for a number of years, in the end the solution was relatively simple without fancy electronics or timer circuits

yeah but the valve opens as fast as it cycles.. so in other words it is quite slow when compared witha typical piston valve

I disagree, the piston always opens at the same rate - the difference in cycling rate is now long it takes the piston to re-close, obviously with higher flow it will be open for longer and you'll potentially get more power.

Sorry for rebringing a old thread, but what materials did you use for the bolt

As explained by PM, this is a simpler way of going about it: http://www.spudfiles.com/forums/full-au ... 10217.html
