KC-02 Threaded 3D Printed Spiral Outer Barrel

Thread: 14MM Negative (-14mm)
Professional installation recommended.
NOTE: product may arrive slightly warped. Once you insert the inner barrel the item will straighten out.

Length in mm * (+$0.10)

Specify the length you would like the outer barrel to be. This is from the base of the barrel to the tip of the thread.
With a stock hopup, the inner barrel sits recessed by about 3.5mm. So if you own a 250mm Inner Barrel, a 250mm Outer Barrel will be the perfect choice as the inner barrel will sit just inside the tip of the threads.
