The takedown mechanism was the creation of Morris Melani, a very gifted machinist and guild metalsmith. It has no protrusions outside the profile of a non-takedown rifle and works great. It has a spring activated sliding bolt that locks the barrel at an indexed position into a slot milled in the front of the action. When the bolt is retracted a second spring locks the bolt into a detent at the rear of the bolt movement. When the barrel is screwed fully in you simply press the button at the bottom of the forearm in and it snaps forward into the locked position.

Here are some pictures of the mechanism.
