Would a 0.5" riser or a 1" riser be needed for a CQB style M4 with lower sights?ex. http://www.amazon.com/gp/product/B004...

A. 75 and 1 inch riser both worked for me but I'm not so sure about a. 5 inch riser? A safer bet is the 1 inch.

I think it would depend on the scope. I bought this to put on my AR to raise my Eotech 512 over the front sights. It didn't work because the Eotech has a large fastening knob on the side which got in the way of the riser. I ended up having to go with the medium profile riser which worked well. Hope this helped.

That depends on if your running back up iron sights. If you are you should get a high riser block. If not then a medium. I strongly advise you run back up iron sights, the flip up type.

I have it mounted on an MP sport. My other red dot needed a riser. The Burris 332 does not require a riser and fits perfectly to the rail.

Depends a lot on the height of the scope rings you use. Generally the medium riser is sufficient, assuming you have a standard rail on your rifle.

You will need a riser. I found one at Academy for about $30.00. Works great and scope is very accurate.

yes, that is what I have, but you will need a 1/2" riser to cowitness with your front A2 and rear MBUS sights

I would recommend a 0.5" riser. I used the risers which came with my Bushmaster, however Truglo sells both a 0.5" & a 1.0".

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.

No, you will need a riser. I bought the NcStar AR15 Weaver 3/4-Inch Riser (MARF) from Amazon for $11.99. Works great.

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.

No, if you have a flattop AR there is not enough clearance to view through the see through riser. I have a flat top AR with fill up front and rear sight. I'm looking at getting the 45 degree offset front and rear sights. this will allow me to the scope on the rail and use the 45 degree iron sights. I hope this helps. There is just not enough clearance on this 1 inch riser and use 90 degree flip up front and rear sights.

I don't believe you would even need the riser on the 10/22. I assume you would mount the picatanny rail or the rail which came with the rifle on top of the receiver and then the optic on top of the rail. This should give you the perfect sight alignment without the need of any riser.

Yes, the picatinny is how it is mounted. As for the sights, it would be totally dependent on what kind of scope you are using. I personally used a Bushnell 3x9x40 with this riser and my sight lens had roughly 1/2'' clearance above my rail.

The riser on this model is 1" I typically use a .8 or .75. This is set for what is called a 1/3 co-witness. If you could use a lazer chamber bore sight. it may help. What I am saying is the mount is a bit tall. This might be the issue. I will say that I have mounted probably 30 of these units and I have never had a bad unit, I have had bad mounts.

Yes this will raise it 1" higher. I have a 50mm scope and had to buy this for the same reason and also lower the co-witness of the a2 front sight

It comes with a riser that will work just fine.....if you get a Magpul MBUS it will co-witness nicely.
