What I got here is a Clamp on Cobra sparkarrestor.. Its semi-polished and seems to be new (Not stating it is new). There is zero carbon build up on the inside but it does have some minor dents in the end. I bought a lot of them off ebay and this is a extra that I dont need. It fits Toomey, CPI, and Shearer.
$45 shipped (This is for 1 sparky)
