ARPlatformFan's Review of EOTech OPMOD EXPS2 Holographic Reflex Red Dot Sight

I love this EOTech EXPS2 Green Reticle – even though it is seriously pricey! It is worth it IMO. But I knew it would be before I purchased it. My tactical defense instructor let me test his custom AR-15 build which was equipped with the EOTech 512 and I was amazed how much easier it was get a sight picture and how the reticle design made aiming less tedious than with red dots I had installed on my LWRC DI 556 or my Black Rain Ordnance AR.
This optic was a huge upgrade from a Sig Romeo5 (LWRC) and Sig Romeo MSR (BRO) – granted the EOTech represents and equally significant jump in cost. As noted in other review, when you get older and your eyes aren’t what they were when you were 30, the larger holographic reticle helps you focus more precisely and quickly on the target than classic red dots. And I came to appreciate that the green reticle is noticeably easier to see (I had purchased a Trijicon LPVO for my other LWRC which also had a green reticle, so I was comfortable with the choice). Shooting with the EXPS2 OPMOD is a joy compared to my other red dots – and they were pretty good. (I did retain my Juliet 3 magnifiers on both ARs after selling my Romeos to friends who had no red dots. The Sig Juliet-3s were very compatible with the EOTech EXPS2; co-witnessed fine and were more than adequate for my purposes.)

I confess to being really impressed with quality of packaging for the unit. I liked that the instructions were complete and straightforward. I consulted my instructor on where to mount on the rail, and then completed the installation without much fuss and I am no gunsmith. With some extra time spent checking out YouTube vids about the EXPS and consultation with my range instructor as to best mounting location on the rail, I completed the install without much fuss (he handled the zero-ing once I was at the range). It zeroed fast. And nothing changed after shooting over 300+ rounds that day, and during every range session thereafter.

In sum, the EXPS2 OPMOD is pleasing to the eye, has rock solid construction, painless to install, and super effective in its role. I guess it would be completely perfect if it had ‘shake awake’ feature but the lack of that capability was not a showstopper for me. But overall, it is more a 5 than a 4 on the rating scale at the end of the day.
Pros:
  • easy to use
  • Feature packed
  • high performance
  • Durabilaty
Cons:
  • price (you get what you pay for)
Best Used for:
  • ar 10 ar 15 , other sporting rifles
