Is this set up for true co-witness height or lower 1/3rd? (only difference is riser size) Because I need the lower 1/3rd with the taller riser.

True co-witness, if your optic has a riser you may want one for this is well- after owning this one it's great but not with a BUIS installed, wish I woulda spent the extra $50 on the larue

According to vortex, it is lower 1/3, not true co-witness. http://www.vortexoptics.com/product/vortex-swing-mount-for-30mm-magnifier

I ended up with mine about 1 inch higher. The amount of sag will depend on the preload setting you use, your weigh and your riding position. So you just see what works best for you.

I used this riser to give me an extra half inch that i needed for my scope which worked out perfect for me. I doubt it will be to tall for you, it all depends on how much elevation you need to clear your front sight for your red dot. For a scope on the other hand , that all depends on how your specific cheekweld is in relation to how high you need your scope to sit. Hope this helps.

I think the legs that run down the middle are too close to use a riser on each and too far to use just one riser for both. Also the frame sits pretty high anyway you might not need them.

I had to low mount on my Strikfire for my Mini 14. I switched the sight to my AR and added this cantilever mount. This mount is offered in absolute co-witness and 1/3 co-witness. I went with the 1/3 and loved it. Not sure if this answered your question or not but yes, you can remove the low mount that came with the sight when you bought it and add this mount to change the co-witness. http://www.vortexoptics.com/product/vortex-cantilever-30mm-ring-1-inch-offset-absolute-co-witness

I don't think this would be the best riser for a 3" round leg. I would try something different.

Not being a gun enthusiast, I don't know what he means by CO-WITNESS. I did not mount a riser on mine.

Hi- If you use only the smaller riser from this set it would raise your bed only 3" and not 5". This bigger riser from this set is 5". Have a Wonderful Day!!

I just got this stepper and I do wish it were higher. Did you ever find more risers? I tried putting all 4 on one side and then put books under the other side, which worked well enough but kind of lame.

I just measured mine and it raises exactly 5 3/8". You might put a 5/8" block under the raiser to get your exact 6". hope that helps.

Although I did not use on an AR, I use a 3/4" riser on the scopes I do use.

Does anyone know if I need a 1" or a 1/2" riser to use this on a A2 AR-15 front sight? Thanks

It sits high but I still get a bottom 1/3 co-witness with the Daniel Defense fixed rear sight and standard A2 sights I use on my set-up.

Hello, The hardware all depends on the thickness of the board and the thickness of the riser (if you are using one). If you're using a standard riser, you can go with 1 inch hardware, if not, you could use 7/8 inch hardware. Let us know if you have any other questions! TGM

It is a .5 inch riser. It actually measure slightly more than that at the rear because of the 20 MOA cant.
