Nerf Stryfe rifling insert

Untested idea I had (Still waiting for parts to come in mail).

Thought it could be nice to experiment with various accuracy inserts into flywheel cages (Various amounts of striation, degree, ID, smoothbore, length etc.), and I wanted an easy way to drop them in and just lock them in. The stock Nerf muzzle seemed like a good way to do this.

If you want to make your own insert to work with the lock/a given Kuryaka cage, mine have: OD of 16.2mm, ID of 14.2mm and rifling thread has ID of 12.7 (At least the STL does, corner roundoff in prints is a bit weird though), 77mm length.
