Running some Wild 1 bars and looking to fab up some bar ends out of some spent casings. Looked at some A 10 Warthog but they seem expensive and too big. I think 20 mm casings maybe a bit small. The inside diameter of the bar is 13/16". Also buying just a few seems difficult to locate....Any ideas?

 

You don't have to use a "large case" to plug the entire bar end,, you could just drill the right size hole in the grip end and fit anything you want in there,,
popular is 223, 45acp, 45colt, 30-06,,,,,
look here for dimensions;

Yeah but I want to fill the whole bar end. Think it would look BITCHIN

 

And the just where do I purchase such a large caliper piece of brass?

 

The end of a 20mm case is pretty big, you gotta remember that number is the bullet diameter not the brass itself. Ebay is your friend or hit up a local gun show and bring your ruler.

 

The outside case dimension on a .50 BMG is .840, that's gonna be pretty close.
Easy to come by, and cheap.

 

Any army navy surplus stores nearby?

 

Google "Bullet stash tubes" Might find what you want there.

 

20x102 is over an inch at the rim. A .50 BMG is .804.
