I'm talking a mount that would fit into a female dovetail slot like the one on the Sig 556 gas block not the male dovetail on the XCR. I'm thinking of going with one of the same plane systems like the HK416s and was wondering if anyone knew of a current offering along the lines of a picatinny mount that would fit into that dovetail slot. It might just be the ticket for the 556 without resorting to the added weight and cost of the Samson rail. I'm getting tired of waiting for the cottage industry sights that are supposed to be available soon for the 556.
