It really all depends on the kit though and if the previous owner butchered the parts together to get a cool look, found out it didn't work right, got frustrated and sold it.

For the optic the easiest will be just an extra rail riser to boost it one step.

I think I saw the ad for that gun and looks like it had the scope mount used to bridge between the rail and the upper so the rail wouldn't move.

I emailed Knightsarmco to see if I can purchase the tool separately, and ill probably shoot the P.O a pm too. Yeah you are thinking of the same gun. I only noticed that after I removed the scope when it arrived.
