I have one on a 20in SPR .223 Wylde upper. I really like it for what it is, an entry level FFP mil/mil scope.
For the price it's hard to beat.
It's a sub MOA rifle but I use it more for 200-400yd plinking which I think the scope is perfect for.
I were looking for a scope for a dedicated long range rig I would definitely go with something better though, SWFA or Vortex.
The main con is that doesn't quite have the clarity of a high dollar optic.
But that's about all I can think of. Holds zero. Resettable turrets. Positive clicks. And like I said for the price you can't beat it.
PA makes great stuff. I have 3 of their red dots and their 1-4x as well. Although I don't think the ACCS reticle is for me.
Also if anything goes wrong with their products, even something past their warranty, they'll take care of you.
