Bushnell 3x magnifier - Bushnell AR Optics 3x Magnifier

I purchased this magnifier because of the advertised extended eye relief. Bushnell web sight states the eye relief is 3.5 inches which seems pretty accurate, and far more than others I've seen. Mounted it on my AR behind my Eotech sight and put about 150 rounds through it this weekend. Unit performed well with no issues. The long eye relief makes shooting very comfortable without having to collapse the buttstock. Glass seems pretty clear, and flip mount seems pretty solid. Looking forward to seeing how it holds up over time with hard use. Still tweaking the mounting position to see where I like it. 4 star rating could change up or down over time with use, but so far, so good.
