Greetings. Interesting & timely topic. I too am looking for a holo reflex sight for my M&P 15-22 and like you I can't see spending some $400.00 on an EOTech or Trijicon. I started my research looking at/reviewing:
ADCO Mirage Solo
Aimshot Reflex
BSA Pano (PMRGS)
Burris FastFire II
Osprey Tactical Reflex
Sightmark Ultra
Truglo Reflex
UltraDot Pan AV
Based on reviews and dot size by today I had winnowed my list down to:
ADCO Mirage Solo
BSA Pano
Burris FastFire II
UltraDot Pan AV
But after further reading I scratched the Burris from my list. I think it's gonna come down to the UltraDot or BSA. Don't know that I want to spend $170.00 or so on the UltraDot, but, you get what you pay for I suppose. And it's made in Japan vice China. On the other hand, the UltradDot has 1 MOA adjustments and the BSA has 1/2 MOA adjustments. Certainly we're not talking benchrest accuracy here, but still, 1/2 MOA would appear to be more accurate. Whilst I'd never buy a BSA scope (But then, why would their sights be any better?) I may just get the BSA and use it for awhile, then put it on my Ruger MkIII and get the UltraDot.
I'd be interested to know what you ultimately decide to go with, and what your thoughts are after use. I'll do the same. Luck to ya.
Cheers,
Mark
Edit- Okay, took the plunge. Just ordered the BSA PMRGS (Red & Green reticles) and spare battery from Adorama Photography (
www.adorama.com). $72.00 total including shipping (Sight $68.75, Battery .95, 5-7 day shipping $2.30). Will post a review when I get it and use it.
Cheers
