Scorpion evo carbine upper receiver (both sides)

thingiverse

this is a scorpion evo. it is a receiver, i think that is pretty obvious. this was originally made by AWCY (are we cool yet?) I then downloaded this from Olga the ogre here on Thingiverse. but the downloading was complicated and there was a lot of zip files and step files, so I thought i would make this simple by uploading a upper and lower stl files. this is the upper receiver, here is the lower: https://www.thingiverse.com/thing:4919933
