Simple and to the point review. I bought the SLX cyclops due to astigmatism and replaced a more expensive trijicon MRO on my Colt LE 6940; it was well worth it as an option.

Meh. … uses a pretty standard China OEM design that gets changed slightly for each company they supply it to and same old internal electronics just interfaced a little differently externally of the China OEM design.

So nothing really innovative.

In reply to Peter Gunn. Have you tried running one with a magnifier? Because of the extended eye relief you don't have the point of aim shift that early models had. I spent the better part of a day at the range confirming it for myself at varying distances out to 300 yards.

I have a couple of these Gen II Green ACSS MicroPrisms- one on an M1A Scout Squad and the other on an Adams Arms SF-308 16″ piston AR, and I absolutely LOVE them.

I’m using a Cogburn MicroPrism mount on the M1A, and by adding an XS Sights Low Weaver Backup Ghost Ring Rear Sight on the scout rail (in front of the optic)- I have lower 1/3 co-witness with the iron sights through the optic… giving me the best of both worlds on the hard-to-do Garand action!

I have been so impressed with my PA SLx 1× MicroPrisms that I’ll be putting one on the Galil ACE Gen II 5.56 Carbine that I just picked up- they truly are AWESOME optics.
