Dewey,
Thanks for the critique, I'll be blushing for a week.
The lever terminus is a hollow and a button cap has been added to each side. The buttons will be nitre blued after they are engraved. The lever will be case colored. Hope to see an interesting contrast.
Yes, this is a take down, a very clever design by Morris Melani that we collaborated in . I was a backseater in F-4s for some years and a standing joke was that the airplane needed two people because two half wits made a wit and that could make the plane fly. We appear to be a good crew.
The barrel locking bolt is loaded with a spring that lifts the bolt into a detent when the button is moved back. The barrel and forearm assemble can then be screwed out. To release the bolt you need simply depress the button and the spring at the back of the bolt moves the bolt forward and when the barrel is indexed to top dead center it slides into the slot in the face of the receiver and locks up the assembly.
Here are some pics.
The take down housing is dovetailed into a lump that was created when the barrel profile was created on the HAAS.
I'll try to get links to alternative photo hosting done later this week.
