Incredible magifier at a very attractive price.

I am building an AR-15 for my son. I bundled this 3x LER Magnifier and swing mount and chose overnight shipping and got it the very next day. I installed it and everything went together perfectly. I put the rifle to my shoulder and after a few very easy and minor adjustments the sight picture behind an Eotech 517 was brilliant crisp and very clear. Absolutely no smudging of the center dot inside the reticle. Compared to my Eotech G33 magnifier on my Daniel Defense the sight picture is so close to being the same! Sure it's a bit larger in size than an Eotech but not by much. The body is very rugged and the glass DOES collect as much light even on the overcast day that we are having today. Honestly If I had known then what I know now.....I would own 2 of these things and saved over $400!!! Way to go Primary Arms! Nice piece of hardware for such a low price!!! Get one and pat yourself on the back for the $$ you just saved!
