I bought the Troy rifle battle-rail, which makes my Samson HK-style gas-block mounted front sight useless. It's been on the rifle about 18 months, it's in very good shape. I'm asking $60, which includes USPS shipping. Thanks!
I don't believe so; I bought the Samson gas-block front and the Samson 40LP rear BUIS after conferring with Samson. I really don't know if the height of this sight would line up with the SIG diopter rear; my guess is it wouldn't; it sits very high.
