unregulated metal bullpup: ADR-50

Unread postAuthor: Brian the brain » Tue Nov 13, 2007 4:06 pm

Introducing the next step in bbmg's: the ADR-50

An acronim for Alien Death Ray- 50 bar
This weapon uses unregulated CO2, at 900 psi, to propell the lead '.177 bb's.THe pressure washer handles it like it's nothing.The valve doesn't freeze up!! ( ýou had me worried there for a minute).50 bar turns this from a strafer into an extremely powerfull raygun, hence the name.
The CO2 bottle looks a bit weird, hence the alien bit..
It is actually very comfortable and very lightweight.It feels a bit like an Ingram ( mini UZI) but with a stock.
I just had to go for caliber .177 because of the availability of the ammo.
Sorry to disapoint some people who might have hoped for a 10 mm version
It's configured like a ( a very extreme) bullpup, wich combines a long barrel with a short gun.
Say what?!?!
The barrel runs all the way through the gun, from the bottom of the shoulder stock, up and through the body.THe barrel is actually longer then you would find on a regular spring-piston air rifle.

The bb reservoir is located in the shoulder stock, and can be accessed via the top part of the Tee.
It is currently unfinished and in this configuration even untested ( 6mm airsoft worked like a charm though)
I will drill out the part ( stem?)wich connects the bottle to the handle because as of now it restricts flow.
I will use epoxy resin to make it look a lot better, I might fill the body with epoxy too, apart from the airchannel running through it.
Color will be flat black.( DUH!)

Comments are welcome.

It was specially made ( or actually adapted) by the manufacturer to accept the fittings I wanted.

I hacked off the "cosmetic disturbances".

Interesting, cant wait for something like this to be finished. How big of a magazine will this be? It looks like 900 psi will drain the resivior pretty fast. Maybe you should go with a Thomsom M1928 submachine gun drum style resivoir like this

The guy told me M22 is the standard threadsize( weird, but okay)

I'm pretty sure a M22-1/4"reducer will hold the pressure since it would be encased in the standard fitting anyway, so you could still use it, I just don't know if they are available..

Maybe different brands use different fittings, I don't know...

The reservoir might be enlarged.Although I love the Thompson, I wanted to take the bullpup design to the extreme, just to see what it would be like.
