I'm confused. The ones with the multi cal insert were the old ones which had to be dremeled. Simon (empire) remade them with a shorter feedneck and no insert ridge. Are the ones iisports sells the old ones or newer ones?
Note: While I would love to take credit for his work, I am not associated with Mad Customs!
