well in not set on NERF darts its just that they are a readily available ammo for me.... living in Aus getting BBs is kinda bit difficult without going to ebay, and i dont to really do that if i have the choice..... but no they dont need to be Nerf darts i just thought it would be an easier option....

thanks jack...... hmmmm i always thought that this type of design would give you only one shot... without a compressor filling it would it not empty on trigger squeeze???

clear it up for me.... to noob to get it hahahahah

hey guys because i plan to use a magazine to load the ammo.... does my barrel need to be 100% airtight??? like after the sprinkler valve?

A problem for you is going to be power consistency.

thats true......hmmmm.......... :? would having a increased in pressure help? or.... like since it will only shoot 6 darts before a reload / re-pump i believe it should be enough :? ..any shots after that will be just bonus i guess?

hmmm so far ...

good ideas guys..... :) nice...... i really like Big-E's thunderbess there just only one thing i dont get..... im not to sure how the concept of the blow gun on the brass tee join works..... can someone please explain this to me briefly in noob-ified terms so i get a general idea on whats happening ...

Yeh i was trying to think of a way the mechanizes that part of it.....but yeh any ideas how i could like bypass that kinda stage..... will getting rid of that 2nd chamber idea and just making it connect straight to the main tank work? asin when i squeeze and let go will there still be left over air ...

My first post be nice 8)

Would anyone be so kind as in to point me in the right direction...... what im trying to do is build a semi auto Pneumatic that preferably runs off a tank / chamber / reservoir of compressed air.......and not a compressor.

ive looked around and found things here and there ...
