What is the height from top of rail to the center of the glass with factory mount without the riser piece?

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

It depend if you have a high front sight and to fix that you need to have a riser 1/2" or 3/4" depend on your preference.

4 inches without mounting brackets. We used velcro to install them in a CJ5.

around three inches, if you slide mount rings towards center, maybe around 2.5

The gas block is way to short to attach this to. The riser rail is approximately 6 inches long where it attaches to the rifle.

1/2 inch. That is from the part of the mount that is flat against the rail to the bottom part of the curvature of the ring is 1/2 inch.

no need for a riser, youll see the front sight but its no distracting, the eye relief is on the short side, youll have to mounted all the way back on the rail.

The screws are pretty short. They only extend out from the back surface of the rail by 3/8 of an inch. I measured them.

As it states in the description, its centerline height is adjustable from 6 to 8 1/2 inches meaning it extends 6 to 8 1/2 inches below the mounting location on your gun.

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.

I apologize for the delayed response on your question. Basically once mounted the top of the rail is 5/8'' from the top of the M91 barrel. It is a nice fit but unfortunately for me it will require me to get a cheek rest as it does raise the scope up a bit. This is also variable according to the scope and ring height that you mount on it as well. Let me know if you have any other questions.

The rings I have are about 3/16" above the rail. Meaning that they are obscenely low if you are wanting something tight to the barrel. If you have a scope with larger lenses you may want to go with a midrange height mount.

I have a similar sight, same style, different brand name. This riser gives the actual red dot a height of 1.5 inches above your flat top. Also,the 5 slots line up to the exact length of the mount on the bottom of the sight. Hope that helps.

It is 7 1/2" from inner rail to bumper. I have this mounted on the bumper of my 5th wheel. The bikes clear without any problem.

I'm not sure I understand your question, I had to use different rings on my flat top rail. The ones I bought were 1 inch high.

I am not sure just exactly what you are asking, but hope the following might be of some help. I installed the subject riser on an M4 carbine I built up using a Mil spec A3 upper receiver. I just measured the dimensions of the rail widths and found both the riser mount clamps and the scope ring clamps measured .833" wide. This unit was advertised to be compatible with either a standard picatinny or a weaver rails system. I believe it is. I did not want to break down my system to determine maximum widths possible, but I am sure it would go a few thousanths of an inch wider on another rail if required.

I have this riser mount in my S&W; M&P; 15 with a regular 32x scope and the front post doesn't interfere with the scope view. I'm sure you won't have any problem with the auto range either. Without the riser the post is just below the center. I also have to say this little riser is surprisingly well made and for the price is a steal
