Primary Arms 4X Compact
Ordered over weekend. Arrived today (Wed). I had heard Primary Arms is quick shipping-- it's true.
Finish: Not all that impressed. Body housing has kind of cast imperfect finish.
Fit: Sits low. Only about .5 inch above rail. Difficult for me to get low enough to properly see thru. Maybe a YHM .5 inch riser would be the way to go.
It has three rail thingies

Not sure what good they are... but they're removable.
Works: The reticle is very fine (kinda like some of the ACOGs). The reticle has no detectable cant. When illuminated, the reticle stays sharp and fine. The focus ring works great. There is no distortion that I can detect. The scope is clear and light is on par with most cheap optics, maybe a little better than some.
For those with Sig522... the scope height is absolutely perfect (for me anyway) with Sig's lowered stock position. That's where this scope is going.
I took some pics. I found it near impossible to get my camera on the reticle but I got one shot... kinda sorta.
