Coax breechloaded design

Unread postAuthor: Brian the brain » Thu Jan 12, 2012 3:24 pm

based on Al-xg's and petitlu's design
I came up with this idea.

It eliminates the use for precision ammo and wastes less gas after each shot.

In essence this design would enable us to use any "conventional" firearm-like loading mechanism.
In this case I show a basic breakbarrel concept but it could be replaced by a boltfeed.
Either manually operated, semi auto or even full auto.

Offcourse the coax reservoir would have to be filled from a HPA/CO2 bulk tank or something like that.
I imagine a semi auto pistol running off a 12 gram.

Thanks to AL-XG and Petitlu for the inspiration!!

The cartridge-like part is hollow and moves forward to disconnect the barrel ( wich works like a balanced piston) from the rubber backing washer on the fromt of the backplug.
The cartridge is not part of the ammo, but of the valve.
The cartridge had parts cut out of the head so the air can push on the barrel itself, untill it disconnects as it slided forward.

This is just the raw concept.
many things could be changed like a rod running over the reservoir connected to the barrel, wich could be used as the striking pin.In this case you wouldn't need the cartridge thingy,

Then just add a magazine and a boltmechanism of your choice.

Oh and please respond...I'd like to try this idea and I need feedback to avoid unnessecary failure... :D

I just thought of cutting a notch out of the pipe, and doing a slide forward bolt action mechanism..

comic sans, seriously?


The way you propose using the "cartridges" reminded me of this, without using a detent.
