Very Happy - great value April 2, 2014
Reviewer: Dennis from Peoples Repulik of Kalifornia  
I did a 4 Day Practical Rifle course with this scope.  Very happy with the quality and the reticle is very cool.  Can't wait to try some longer ranges to see how the 400/500/600 dots work.  I also mounted a Bushnell Fast Fire on top as shown in one of the pics on this site.  Honestly, it's a little high, ok for a quick reaction sight i suppose.  It didn't use that at all during the course.  I found the 2.5 mag worked fine from all the ranges we shot.  200/100/50/25/15/7 yards.

great cheap acog alternative April 2, 2014
Reviewer: Anonymous Person from texas  
I didn't expect to like this scope as much as I do. The glass is really quite good--significantly better than a Burris AR-332. Its better than the 1st gen PA 1-6 as well (2nd gen are not out just yet) The reticle is almost nuclear bright and helps you judge range. Overall build quality: well built, this is not flimsy gun show junk. And if you're wondering if a fixed power scope is ok at close distances, yes it is. You throw up your rifle and get a sight picture almost instantly--eye relief and eye box are excellent, ie if your head is not positioned 100.000% perfectly you still get a good sight picture.

Ideas for future improvements? How about an AA battery tube like Browe uses for longer battery life. A lithium AA is pretty lightweight if that's a concern. Or when Trijicons acog patents expire (should be fairly soon i think?), how about fiber optic illumination to help conserve battery life. A dual sub/super 300 blackout reticle option like Browe would be awesome as well.

Just Right April 2, 2014
Reviewer: Anonymous Person from IA United States  
This was just the scope I was looking for. Perfect magnification, great reticle, daylight bright illumination (even on bright, clear, snowy days), compact length (its a bit tall and definitely heavy). Very easy optic to use, very quick. I have no problem hitting broken pieces of clay pigeons at 100 yards, one after the other. I find myself going through ammo very quickly compared to using irons.
Feels quick to use at 25 feet as 100 yards.  

Purchased with the quick release mount(just before the free give away but it was still worth it). Mounts over mbus with no clearance problem, has kept zero every time I remove it when transporting. No issues seeing past my fixed front site(its just a blur I don't notice when focusing on target)

Has kept zero with 1500rds through it so far. No defects visible on glass or reticle Overall, if I had to choose between a 1-4x or this optic, I would get the 2.5x again.

Best optic for the money February 19, 2014
Reviewer: Joseph Jennings from Bucks County, PA United States  
Got my scope in today and I absolutely love it! I was very impressed with the glass clarity, the overall construction of the optic, and the design of the reticle. The off set mount allowed it to sit perfectly over my Magpul MBUS sight, now I can't wait till I get this baby zeroed in and see what she can do. The guys at Primary Arms certainly hit a homerun with this product

Perfection, how else to describe February 10, 2014
Reviewer: James Lucas from Carthage, NC United States  
I mounted this to my AR-15 and was truly amazed at the clarity of the glass for the price. Zeroed at 50 yds and connecting with 10" plates at 300.  Another thing that I thought was amazing is how accurate the clicks were.  On most scopes in this price class ( not scope class as this is a quality scope ) you make an adjustment and POI doesn't follow the clicks.  With this scope no problem. I shot MOA at 50 yds easily with my NV Clip-on also. Works great with my clip-on.
