This extreme DIY build uses custom machined parts to create a Airsoft M134 Minigun. The eye-catching thing about this do-it-yourself gun tutorial is that the sleekness of the finished minigun as well as the detailed instructions which are neatly arranged and easy to follow.
The gun is comprised of different sections such as the barrels, motor, feeder, handle, firing mechanism, etc and the tutorial features full schematics and plans too. The technically precise model is fabricated from alluminium on CNC machines. The artist did his design modeling on Solidworks and total fabrication costs came to about $1200.
