I got a flat top carbine I put together years ago. Well woot had some PFI red dots for cheap so I got one. Problem I didn't even think about is the rifle has the typical military A2 style front sight post and gas block, rear sights just as tall. The RD is a 33mm tube with what look like the lowest rings possible the tube pretty much sits on the rail almost no gap.
Anyone know how tall of a riser would give it a lower 1/3 co-witness? I'm thinking 3/4" but figure someone's done this before.
