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.

A 20 oz CO<sub>2</sub> tank is not too expensive.

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" ;)
