OOPS! MY MISTAKE! I was multi-tasking when I put the barrels up and misstated the chokes. THEY ARE NOT .028/.018. THEY ARE .040/.030 (TOP/BOTTOM). Again my apologies. These barrels have never been modified and are just as they left the factory.
The barrels are located in northern California and I will pay shipping anywhere in the southern 48.
Just as an aside I thought about having them choked but I bought them originally for bunker and just realized that I am too old to move 32's around quickly enough for bunker so I am selling them.
