Primary Arms 3X Red Dot Magnifier Gen III
NOTE: Make sure that the mount you choose is capable of interfacing with the 30mm ring on this magnifier, because the objective is larger than the 30mm mounting area. Mounts intended to just slip over a 30mm mounting area and tighten down will not work.

Gen 3, 3x magnifier
Got this magnifier in the mail two days after ordering. Excellent shipping! I have had this sight on my Colt 6920 for about a week and have put 80 rounds down the pipe so far with no issues. I can understand people wanting a longer eye relief, however, I almost always shoot nose to charging handle and I get a wonderful sight picture. I have the magnifier in a standard height mount which matches up perfectly with my PA Classic red dot. My only complaint is the weight, but for 70$, I shouldn't be complaining. Fantastic optic from a fantastic company!

Great quality AND service! Purchase arrived ahead of schedule and quality exceeded expectations.I'll buy from Primary again.
I am having a hard time getting the magnifier to focus through my red dot. Without instructions I dont know if I am missing some kind of fine adjustment or not. Also the red dot is very distorted through the magnifier.I am going to return the item if I cannot figure it out on my own.
I bought this magnifier as a cheap alternative to the EOTech magnifier for my wife's AR-15. Between the two of us we've put almost 500 rounds through the rifle and haven't noticed a single issue with this optic. I combined it with a slide-to-side quick detach mount from cheaper than dirt and the Primary Arms multi-reticle 30mm red dot on a cantilever mount. Neither of us could be any happier.
Clear lens good magnification
I bought this magnifier to go along with my PA Red Dot Scope (Classic). It lines up perfectly with the scope, I upgraded to the Flip to Side Mount. Lens is clear and 3X is enough for 100yds +. Only criticism is the eye relief is not great, you have to have mount it pretty far back on the rifle.

I cant really complain because it was "free" (I chose to pay a little more for Primary Arms' outstanding service and for the "free" magnifier with my EoTech 516 purchase) but if I could do it over I would go with the Extended Eye Relief version. Not necessarily for the eye relief (although it could be better also) but for the smaller size and, I believe, weight. The objective "flare" in front of the mount makes it a lot longer and bigger than I expected. It works fine though...but I have to move the EoTech forward more than I would use it normally to fit the magnifier. But other than the size and the relatively poor eye relief its good. It certainly seems sturdy! Go with the Extended Eye Relief version though!
