Will this Loading mechanism work?

Unread postAuthor: pyromane93 » Mon Jan 23, 2012 4:57 pm

Hey Guys
i've made a semi-auto BB Airgun with a qev and slidevalve..
For now i'm looking for some Ideas for the semi-auto loading
i drawed a picture of the mechanism, will this work?

Image

When the Air pushes out of the qev, the Piston will be pushed forward and fires the BB. this would be every Shot.

Here is the Video of the Gun:

Good build, its a sturdy looking construction and looks well built.
As for the loading mech what you have proposed seems extraordinarily like the ever so popular tried and proved, blow forward loading mechanism that we are seeing becoming commonplace on this site, especially on small-bore pneumatics, such as your own. :)
I have attempted to find the link to jsr's original thread on the design, which would be quite useful for you. but my skills in using the site search are quite shoddy, so I will leave that honour to someone else, that is if can't find the link myself. :)
And welcome to the forum :D

That is a blow forward bolt, all you need now is a spring in the magazine to push the BB's into the barrel and a dent to stop it rolling out the barrel.

Why such a huge valve for a tiny barrel?
