Looks good, but two criticisms
- a moving barrel will compromise accuracy, why not have a bolt action sleeve instead?
- the main tank size is too close to the firing chamber, it won't be good for more than two or three shots.

Could you post a slightly amplified view of the bolt
I think he means a simple blow forward bolt

Actually its just a manual bolt with a return spring you need to cock it every shot

Why not take the extra step to make it blow forward and have full semi-auto one-shot-per-trigger-pull.

Why a blowforward when you can use a hopup and original airsoft mags ??

As tiny as the drawing is, the BBs look copper coloured... I think he intends to use 0.177"

thx kind of hard for me to make since i only got basic tools and it will be operating at high pressure so it has to be safe think i will make it manual an maybe upgrade it later.
its still better then the vss sins its semi auto
