From the old thread (http://www.uzitalk.com/forums/showt...edneckengineer-quot-For-Details-Of-Your-Upper), here's the info:
I spent some time designing stuff, making stuff, then throwing away stuff.
This is my current upper design, the UltiMac.
The upper uses an internal recoil mechanism, no drilling in the rear (unless you're in to that sort of thing, I don't judge)
Will not work on SAPs, open or closed bolt.
Will not function or fire without registered lower receiver attached.
Uses AR15 bcg, barrel, and handguard.
Modular design, magwell is removable and can be replaced with:
AK47,
AK74,
AR15,
MP5,
UMP,
PPSH41,
Suomi,
Glock,
Colt,
Thompson,
M1 carbine,
Greasegun, etc.
Scorpion EVO (enough people asked, so I'm adding it)
7.62x39 in AK mags:
5.56 via AR15 mags:
Special thanks to XRayGuns and my friend Brian Butler for their help in designing this.
