Good recomendation - Lucid Optics 2x-5x Magnifier for Red Dot Sights, Stand Alone

I recently purchased this item to add to my colt M4. I combined it with a twist away mount and have had it on the range a couple times. The product is great! Clear lens, clean look and best of all adjustable magnification. The price was great as well and did not result in me having to pass on a car payment to get the magnifier. My only critique is that the eye relief is not very forgiving. It is rather specific and quickly goes from perfect picture to not picture depending on how close your eye is to the lens. Other products may have this figured out but will not have the adjustable magnification.

Thanks Lucid and Optics Planet!!
