AR-15 M4A3 Upper Receiver
by tenlow, published
This is an M4A3 upper receiver from an AR-15. After printing a lower I wanted to print an upper more or less to see if it would fit.
All I did was take the IGES model from CNCguns.com and make it a sliceable STL.
This is a purely decorative piece. The argument over whether or not lowers can be printed and used is valid, this piece however is completely unsuitable for use in a live firearm.
I printed the model upside down, but you might want to rotate it to print in a different orientation.
