Got the new Vortex Razor AMG UH-1 in and at first, I thought this was going to be too big for the MPX, but after throwing it on there, I think it was made for it. So far I really like it, haven't taken it to the range yet so, that will be the tell, tell. Here is some quick pics I took late last night, and my camera sucks, so overlook the quality of the pics.

How crisp/ clear is the reticle?

How is the tint?

Very clear and crisp.  Nice wide large lens to get on target fast.

Leupold LCO works great as well. Picked mine up from Optic Planet for $620 which include a $100 gift card. 

Cool to see that these are finally shipping out. The button position and qd mount looks great. Have you tried out the USB charger yet? haha

Soon as I get to the range sometime this week I'll update this thread on how the UH1 works with the MPX and also get better pics. I just threw it on there last night and took some quick pics with my phone camera just to see how it looks on the MPX. The sight window is very clear and large for easy targeting, even though you can not see it in the pics. One of the interesting things about the design is that the windows have nothing to do with the hologram. You could completely bust them out and still use the sight. They really are only there to waterproof the internals. That being said, the Vortex uses polycarbonate lens with a special scratch resistant coating.

The pics I posted does not give this thing justice, I will get better pics and throw them on here.

No, have not tried the usb charger yet, it came with regular battery but you can buy the rechargeable one, but what I have read is it does not last as long as a regular battery.

How does it compare to an Eotech?

This is the First UH-1 I have seen in the wild, you're not a gun reviewer writer are you? How did you get in so early on a UH-1, just wondering as its the first i've seen anywhere.

No, just and end user. But I have a good connection with a Vortex Dealer that usually gets first shipments from Vortex, so anytime a new product is going to be released that I'm interested in I contact him to find out release date and get on his preorder list.

Never owned an Eotech, so can not answer that question.

I had my Eotech on mine for a little bit. It worked well and was comfortable. The "subgun" style aspect worked well with the large ring at the shorter ranges.

Mine is now wearing a Vortex AR optic thingie. I like it. It works well.
