When up, what is the distance from top of rail to top of sight?
1058534
The distance from the flat surface of the top rail on the YHM front sight gas block is .803. The bottom of the arch is not exactly circular, so I would say .800. With the front sight bottomed out, it measures 1.075 from the flat to the tip of the sight. And that is my problem, I cannot get the piece sighted in vertically at 25 yards, I'm shooting 6 inches too high. That's with a YHM gas block and a YHM upper receiver. I am not having this issue with my MI sights on a 9mm upper. That said, I have not eliminated other possible interactions, so it might not be the sight. I'm going to switch them out for a better comparison. However, there have been other complaints regarding sighting in the TI sights at short distances. Guess I could grind the sight post down a bit to correct the problem.

From floor to top of rails is about 65 inches. Im 5 foot (dont have a measuring tape) and the top rail is just a few inches higher than me. Maybe the length is about 77 inches but not height.

No laying flat the rear sight is 1-1/16" off the top of the rail flipped up its 1-5/8 to the top of the sight and your line of sight is at 1-3/8"

you will want to move your top sight up and your windage to the right. Happy shooting!!

Use one that raises the scope over the rails at least 1/2 inch. With that you still be able to sight your scope. Anything more you will have to adjust your aim.

On the lowest setting, the top of our mattress to the lowest rail top is about 19.5 inches. The height from the top rail to the box spring is about 25 inches, so you could do the math if you want to know an exact height with your mattress. Good luck!

from the top of the rail to the bottom of the scope I have about 3/4 of an inch.

I have mine set close to 6" but there is a reverse picatinny rail on the bottom-front of the scope which allows you to reduce its footprint. To lift the scope higher, just add a riser... Great quality, and great value!!!

The over all height of the railgrab is (3 1/2"). The railgrabs (when attached) add (2 1/2") to the height of my roof rails. My bars sit about 4" above (99 Suburban) roof. (roof is curved so depends on where you measure from.

With this riser I can still see the front sight in my optics, but it is below the red dot by a bit, so it may not be high enough for you to use the flip up sight too. Hope that helps....

From the mattress base to the top rail is 13". Put a mattress in and you have around 5 to 6 inches from the mattress to the top of the rail.

Looks like it is 1 7/8" from top of rail to center of glass on mine. Factory Mount, no riser.

Sorry, your question was about the height. I know it is at least 6 inches from bottom of rail to ground, but can measure it when I go home.

The overall height on a flat surface is 3/4 ".Installed it will add about 5/8" from the top of the unit to the arch that goes over the pictanny rail.

The rail is adjustable in height. I currently have it set so it is 21" higher than the cross bar, but it can go up in height another 4". Distance between floor and where the cross bar is 13". User is 6 feet tall.

The sight you are looking at will only work on uppers with gas block. These are a tad taller since the gas block is slightly below the quad rail on a flat top m4. The front sight is also adjustable for elevation.

From the top of the rail to the top of the sight, in the flipped up position, is 1.5 inches. Though I haven't done it myself, I wouldn't be surprised if some shooters use a riser under them.
