BLACK BETTY - HPA Select-fire Nerf-compatible Blaster
THIS IS FUNCTIONAL BUT IT'S STILL A PROTOTYPE, SOME FITTING AND REDESIGN LIKELY REQUIRED TO FIT THE PARTS AVAILABLE TO YOU. PLEASE READ THE FULL BUILD WRITE-UP OVER HERE

I'm not going to go over any kinds of major details here, there is a 13 page complete write-up with pictures at the Imgur link above. I'm not going to do any kind of hardware list here either since it'll likely have to be adapted to what's available to you, read the write-up.
The whole thing was printed on a Makerbot R2X in ABS, except for the sideplates which were cut out of HDPE on an X-Carve 1000mm CNC Router.
I'll eventually publish the source Fusion 360 files, in the meantime the STLs should be in mm and the printing orientation might be wrong. NOTE; The parts labeled as 'REFERENCE' are for reference only and shouldn't be printed.
