Steve have you had a chance to try each of them?
The SOPMOD Program Management Office (PMO) is issuing this notice to all
potential users of the EOTech SU-231/PEQ Reflex Sight, NSN 1240-01-533-0941,
also known as the holographic weapon sight.
1. It was recently brought to the attention of the SOPMOD PMO that there
exists the possibility that the SU-231/PEQ Reflex Sight made by EOTech is
susceptible to failure characterized by the sight shutting off in the middle
of weapon fire.
2. The failure is caused by faulty battery contacts that were incorporated
by EOTech without government concurrence. (See attached image). These
faulty battery contacts are susceptible to wear due to shock while the
weapon is firing. As a result, the batteries may lose contact, causing the
sight to shut off.
3. EOTech has qualified a new supplier of these battery contacts and the
SOPMOD PMO is currently validating this new configuration through testing.
By mid April 2008, this process should be complete. At that time, SOPMOD
will institute a 100 percent replacement of the SU-231/PEQs that have
already been fielded. Maintenance Contact Teams will travel to field units
to either swap out the sights with replacements or conduct on-site field
repairs. As an interim solution, the SOPMOD PMO is currently testing a
field replaceable grommet that will mitigate the risk of failure. Pending
test results, these grommets will be shipped as part of a field replacement
kits to units that have been issued the SU-231/PEQ.
4. The SOPMOD PMO has ordered a halt on any further fielding of this item
until sufficient testing has been performed on sights with the incorporated
part upgrade. For those field units that have already received the
SU-231/PEQ, the SOPMOD PMO strongly recommends not using those sights until
they can be replaced or repaired.
I'll add what I can.
I have an Eotech 512 Rev A65 on my AR and love it. I've used an AR which had an Aimpoint Comp M2 and it was nice... but not my preference. For some reason I liked the Eotech's reticle compared to the Aimpoint's.
Now, I haven't used either in inclement weather so I can't speak to their performance in those conditions. However I HAVE read plenty that say neither fair too well once rain drops get onto the lenses... The Eotech may win there, though, since it's a holographic heads up display... and if there is a clear area that doesn't have rain drops on it, the reticle will still be functional and accurate.
I've only held an AR with a Tri-power on it... never fired it. Just looking through the Tri-power, though, I can see why people like the chevron reticle. I actually liked it. The reticle is also VERY clear and crisp. I couldn't see the reticle when it was just in the tritium mode (as I believe it's only used in complete darkness)... I had to turn on the battery power. Admittedly, I didn't spend much time with it at all and would definitely have liked to.
Honestly... All three are used by LEO/Mil and have been combat tested. And each one is different enough from the other two. So go and take people up on their offers to let you try them out. You'll be able to weed at least one of the three out of the running, simply by test driving them. Going on features alone... if you're going to be using the rifle in inclement weather... I'd suggest the Trijicon first, then the Eotech. But if that's not such a big factor... then it's really just about test driving them and seeing which you prefer.
You're welcome to test drive my AR with Eotech anytime if you want.
