With this mount, is the viewing height of the FastFire adequate for co-witnessing flip-up iron sights mounted on a picatinny flattop?

I bought this for my Fathers duty AR heHas for work. The first thing I noticed is how small of a profile it had. The Burris alone would probably be too short, however on the rail riser I think it would work quite well. It would almost have to be perfect at the right height especially if you were to move the point of aim on the Burris accordingly.

It should work just fine. If not, then add a UTG Low Riser to bring it up. I know this from trial and error. I have a medium and a high riser that were too high.

no there is no room under this sight for seeing your fixed sights. You would need to mont the fast fire to the side.

I think it would, but if you mount it to the upper there won't be enough room to put a rear sight on your weapon. I have angled irons on mine to get around that problem. If you could mount it on the forgrip then it sould. It looks to be the right height but I'm not sure.

This mount is fairly low to the receiver. If you don't have a front sight you can flip down I would not recommend it.

My rifle didn't have iron sights, however with the medium height mounts and the 40 mm scope on a 22-250 varmint special I had less than a 1/8th inch clearance between the scope and bolt handle when the action was cycled. Had to go with the higher mount.

No, the UTG Flip-up has extra height to work on a recessed gas block. It will mount but will not line up with rear sight properly.

That would depend on the height of your handguard/receiver; and I'd buy a different riser. The twist knob on/off is crap, gets in the way of the picatinny slots.

Only if you have rails on the handguard and install the scope about 3 rails forward for eye relief. But if your are asking if this is low profile enought to cowitness with your magpul flip up sight the answer is yes, It is low profile enough and may be too low if your intent is to install a powerful scope on if your handguard has rails or if the hand guard is at the same level of the top of your upper receiver.

Yes, this mount will give you full co-witness. Meaning that the top of your front sight will sit in the middle of the red dot.

My scope (nikon 4-12x40 BDC) sits high enough using the SPR for the magpul folding rear sight to be folded under it (no way or reason to flip it up with the scope mounted). I typically mount the scope before I go to the range and take it off (love the thumbnuts) when I leave, and rely on the flip-ups for home defense. The front of my 40mm scope sits just above the magpul rail covers (ladders), maybe 1/4" gap. I also have a IWC QD mount on my top rail just in front of the cantilever portion of the mount.

Yes, I guess it ultimately depends on the sights and the model though really. I have a Ruger SR-556, with the stock flip up sights and the visibility actually works pretty well looking through this Eotech, approximately 2/5 of the way up the glass maybe? Not right in the middle, which would be perfect, but plenty usable without having to remove the system. I had to move the sights back and forth a little to make everything fit the way I wanted but it looks good.

The center of my optic is 1.57" above the top rail. I'm using this on an SPR type rifle that doesn't have iron sights so I'm not sure about co-witness but you can measure your sights and compare to my measurement.

im not exactly sure since i'm not familiar with your rifle. I have the standard A2 front sight and a rear magpul flip up (probably as you do). I had to switch the highrise to a shorter one (from UTG) to get a better lower 1/3 co-witness. the high rise mount the TRS-25 came with was a little high. good luck

That would depend on your sight and your weapon system. My sight is approx 1.5 inches to center and using this riser on my flat-top AR, I get FULL co-witness (NOT lower 1/3). Since both my front and rear sight fold down, full co-witness is my preference.

Sorry, I don't have the optic right in front of me at the moment for exact dimensions. This particular mount puts a magnifier at the correct height for the raised EOTech optics like my 517. It is too high for standard height( iron sight co-witness ) optics like a 512. Hope this helps. BTW this is actually a pretty solid mount for the money and has gotten a lot of use on a 5.56 AR.

I have a flatop 9mm AR with the this tru glo red dot sight mounted forward on the rail, with the flip up rear magpul sight to the rear of the rail and with the magpul up, it actually co-witnesses with each other, flipped down it's totally out of the way of the tru glo sight!

This Riser will make it a 'lower 1/3', it is probably not a 'Absolute co-witness'. I have a red dot scope mounted on this riser and I can not see my (G36)sights through my scope.

About 4.5 inches if you mount it on the upper receiver you have ample room for a backup flip sights
