JET M4 Flash Hider / Thread Protector

UPDATE [4/16/22]: Increased the diameter of the flash hider to 1" as the previous diameter was too small, and as a result, the threads were too close to the revolved grooves around the bottom of the flash hider. This problem has been mitigated by increasing the diameter.

A quick project I made in SolidWorks. It's just a flash hider modeled after an M16/M4 birdcage style flash hider that threads onto 16mm JET / Spectre threaded barrels.
