Completed it a while ago but enver got round to posting it up.

I had some issues with finding a combustion chamber that didnt blow the cap of. The combustion chamber i used on this gun also doubles for the stock, and the gon is quite comfortable to hold and shoot. Its also quite accurite also. I had one little innecendant where i didnt screw the cap on properly, and the cap exploded of the end and got me right in the sholder at point blank and busted the cap. Yeah it hurt, i make sure its on properly now

Shoots 6mm lead BB's. The scope is 3-9x. I havent had a single missfire unless it was caused with to much fuel, fires 1st time everytime. Lots of fun. Here are some pics, let me know what you think

hey that pretty cool. i would move the igniter up a bit, but it looks really good.

edit- whats the chamber made out of?

The chamber is a multi reducer sort of thing with a 90mm threded adaptor with a 90mm cleanout cap. It just steps down in sizes. The igniter is just zippy tied there till i make a better trigger system, but where it is its nice to hold, cuz your had sort of wraps around it.

I like the multi reducer :)
You should move up the igniter like hi said, and secondly, you should paint it.

wow, you did a really nice job. looks like a real rifle and the scope with cross hairs just adds more uniqueness and replication. nice work :lol:

that multi reducer is pretty wicked, mind telling where you got it and if its pressure-rated??

EDIT: oh, and how much did it cost?

thanks -- storne

Yeah paint is on the way, i just havent got around to it yet. What colour do u guys think? im changing the handle and trigger, makeing it shorter so the trigger is higher, will post it in a sec.

The scope cost me $50, i got it half price :P
the igniter cost me 15$
and the parts cost me about 40-50 or so, not quite sure

The multi reducer came from my local hardware shop. Cost about 9$, and it is not pressure rated. Im in australia so i dont know if you guys in the states get that sort of thing?

Obviously you have little knowledge on how powerful a simple combustion is.
It will peak at less than 50 psi for a fraction of a second, assuming the chamber is completely sealed by the "jammed" ammo

Really sweet gun!!!!

But how long is your stock/chamber?
I tried building a gun like this and the cap always blew off...
