Rear loading combustion (German production xD)

[freder]

Hey,

this is an old combustion I startet to make a couple of months ago.
Forgott a handle for the ignitor - but I gave it a paintjob.

My rear loading mechanism:
I don´t push the ammo down the barrel because I can easily pull out
the "stock" and push the ammo in from the back side.

I cut the potatoes by pressing them threw the pipe in the stock.

Some other specs:

C:B: ~2:1
Chamber: 25 cm long.
Barrel: 60 cm long.
Ignistion: somthing like a BBQ-lighter
Other: Fan + switch in front grip

If you have any questions just ask

I like it
I think it deserves a propane meter though.

Its lacking H&K's aesthetics, but the ingenuity is there, nice job man

I like the concept a lot actually. Looks like you lost a little patience with the tape jobs at the end. I'm with BB, A syringed type metered propane fuel system would be nifty with this.

Be sure you lock that breech plug down well. I could see that thing bloodying your nose (or worse) after a shoulder shot if not.

Well I´m not in to the propane stuff but maybe I´ll try once

@ starman:

Actually you shoulder fire it by using the breech plug as a stock.
So you just have to push your shoulder hard on the plug, hold on tight to
the front grip and jam the chamber between your arm and body because
this gun has a bad ass recoil

Very nice work. But yeah....a propane meter would do it some justice.

haha... actually that isn´t mold. Those are holes I drilled in.
I first thought I could drill in one big hole for the lighted gas but noticed
if I had done that it would have been hard to push the potatoes in ( or somthin else). So I drilled in a few small ones.

Here´s a small sketch of how it works ( not shown: fan, cap, ignition)
