TRUE BLOWBACK (GBB)

[i-will]

it doesn't have to be airsoft. this valve system can be use for anything. why limit it with labels like "spudgun" or "airsoft". a valve is a valve. a projectile is a projectile. this will still work if u make it pocket sized or if u build it as big as my couch.

implement the principals of the gbb. don't limit it to airsoft.

But on larger scale its WAY easier to use a blow forward bolt or something else.

easy doesn't concern me. why do it cuz it easier?

how would u go about building it. i'd use copper.

why do it cuz it easier?

Because it's less effort?

Why do it because it's harder?
Besides, the airsoft style of blowback is inefficient, designed for the flair of the cycling slide.

if it's so hard than don't do it.
