    First time using Tacrig but have been stalking their website for a while. They stock great new products at already low but definitely unbeatable prices (with coupon)!

    Absolutely a beast of a unit! This thing is awesome! It’s like having a HD TV on the top of a pistol! So many options for the radical, plenty of adjustment in brightness. It fit in my ALs holster however it was modified so your mileage may vary.

    Great product. Nothing negative to say about the optic. Very fast shipping from Tacrig. Had the optic in my hands within 3 days. Price was best around as well. Will definetly be making more purchases in the future.
