A unique assault rifle / machine gun design, I'm no gun expert, so don't expect the design to be too practical.
Blend file has one procedural texture to add a rough, textured surface to the gun, this does not come in the OBJ version.
The magazine is not intended to be removed.
Gun is split into 33 objects.
Blend version comes with camera and lighting.
OBJ export probably removed object named and set origins all in one spot.
Worried about using a real design for legal reasons? Then this could be the gun for you!
