the cost would be greatly reduced as expensive metal would only be a about 4" long. the rest can be made of what ever easiest even alumnum.

The cost is NOT in the materials. My .50 cost about $100 for ALL of the raw materials. The action blank runs about $30 for material (remember that #)
For a barrel extension you would need about 4" of steel (1.5" of thread for the barrel, 0.875" of lug in the extension, 0.875 clearance for the bolt to turn into place with 0.75" threaded on the end). Cost for the steel... About $8-$10...
The "action" would need to be 2"od (to match the extension) 1 5/8"id or 1 1/2" id (for bolt clearance) tubing. 12" of 1018 tubing would cost about $25- $30.
A couple $ more total (not a big deal). Where the savings would come in is that it takes me about an hour and 10 minutes PER inch to EDM the lugways. Keep in mind that this is not necessarily the best way to do this. It is, however, the I CAN do them. This is assuming a .50BMG action, which I still don't know if I would want to do that. There are fare more stupid people out there than you can shake a stick at. The first asshat that breaks his collar bone because he doesn't understand what he's playing with and I never will be able to retire!
However, I'd be curious to know if there is enough interest to make it worthwhile to do.
