I own a RRA UTE without detachable carry handle I have had for about 3 years.  In the photos of the UTE2 it appears that the weaver rail where optics are mounted is lower than the UTE.  Is this the case?  How much lower is the mounting  area/rail? .300" ?  .400 ?.  My iron sight picture is at the bottom of the Aimpoint tube on my UTE upper.  Do the iron sights co-witness with the Aimpoint better on the UTE2?  Do the iron sights sit closer to the middle of the Aimpoint tube when they co-witness with the red dot?  I am considering either switching to the UTE2 or different optics that would allow a better iron sight picture.  

Thanks,

The rail section forward of the sight housing on the UTE-2 is A4 rail height, so mounts made to co-witness off of a flat-top receiver would do the same off of it....if there is enough room for them on the rail...which there generally is, but I can't verify it for every mounting option on the market.

So I might be better off replacing my UTE upper with a CARA4?  It sounds like the Bushnell EOTech sight won't cowitness with my early version of the UTE.

The UTE receivers (not UTE-2) are essentially the same configuration as our A4 with a tactical mount installed.  That set up lends itself well to tubular red dot sights, but not to the EOTechs and others that have a base with an optic "window" mounted above that base.  The EOTechs were designed to co-witness when mounted directly on the A4 receiver.  They do work on the UTE-2, which shares the height of the A4.

I keep seeing a reference to a front sight base marked "F" in other posts on this website.  Is the "F" front sight base taller than a regular front sight base?  If it was .100" to .200" taller and I could raise my rear sight by that much, it would move my iron sight picture higher inside my Aimpoint.  That is what I am trying to achieve.  I am not going to be making shots beyond 300  yards with the rifle and a little loss in elevation movement will not concern me.  

 

Nope...about.040 higher, and you probably already have one, just not marked "F".
You really just need a lower ring...but we still won't get true co-witness, just lower third of the optic.  The Tac Mount and UTE (original style) was st up for the extra wide, low ring that Aimpoint used to ship with the optic, and that provided that window.

It would be nice to have photographs of the iron sights as viewed through an Aimpoint or EO-Tech sight on your website !!!!

Thanks !!!

+1000!!!

I'll see what I can do..maybe use the Dominator and Stand alone rear sights and A2 front sight with the EOTech and Aimpoint inbetween them (seperate shots of course).

I installed a see through scope mount for my Aimpoint on the upper.  POI for the red dot and the iron sights is the same.  It also puts my head in a more upright shooting position.  Problem solved.
