Don't overlook the Meopta Meostar R1 1-4X22 RD if you are considering a variable.

It is made in the Czech Republic, but distributed out of NY. I have one and it is outstanding on an AR. Quality is very nice. It is a ture 1X. No distortion at close range. The reticle, 3min dot w/ hash marks at 3, 6, and 9 O'clock, is awesome. The reticle is black, but can be illuminated for daytime or low light use. There is an off position between each of the 7 illumination intensity settings. Plenty bright enought to use in full sun. It is just like an EoTech or Aimpoint, but you get to go to 4X if needed. FOV at 100 yards is around 111ft. @ 1X. Price is around $700 which is a good deal for what you get. It also has a 30mm tube body. 50 yard zero gets your poi within 2" of line of sight out to 250 yards. My load is 8" low at 300. Hold the 3min dot on the neck or use the top of the 6 O'clock hash mark for a poa at 300. Works great.
