    Extend the range of your Red Dot Sight with the AT3 3X RRDM (Ruggedized Red Dot Magnifier)

    No need to choose between the close-quarters advantage of a red dot sight, and the long-range benefits of a scope. Get the best of both worlds with a simple flip of the magnifier.


    • Easy upgrade to extend the range of any red dot sight with 3X magnification
    • Quickly transition between short- and long-range shooting scenarios. Just push the button and flip the magnifier
    • Easy install & removal with Pictainny thumb screw mount


    • Crystal-clear multi-coated optics for a sharp sight picture
    • Adjustment screws make it simple to center the red dot in the sight picture
    • Fast focus adjustment ensures a crisp sight image


    • Sturdy flip-to-side mount with positive locking mechanism, made of durable 6061 T6 aluminum matte anodized finish
    • Shockproof optic with ruggedized rubber shrouding, built to withstand recoil of any weapon, including shotguns and large-caliber rifles
    • Scratch-resistant optical coating
    • Backed by a 3 year warranty

      Customer Service

      cant give a review on the product i purchased because i haven't used it yet, so i am leaving a review on customer service. When i received my purchase i noticed a part was defected, so i called customer service. the person i talked to was was extremely nice and apologetic. I called on Friday and on Monday i received the replacement part in working order what more can i say. Thanks for the prompt and
      great service

      We are glad that you are happy with the service you received in processing the replacement.

      Works fine, looks good, but have not shot with it yet. looking forward to that soon. Has a little play in the lock pin but cannot see that will cause any problem because it does not distort the sight picture. I think it is a great design and I fully expect to enjoy it when I go to the range. Have shown it some friends and they all thought it was great. You might be interested in knowing that I am confined to a mobility scooter and still built my AR15 which has your red dot, iron sights, and now the 3x. Indiana Hoosier says Thanks

      PS: Delivery good except was delayed by the snow storm. in March.

      Great Value

      I'll admit I had doubts------But------not now. The combination worked out better than I expected. It's well made, cowitness, and holds it's settings. Haven't had any RRDM push button problems. Would certainly recommend to a friend.

      Great product

      Perfect it fit my gun exactly and match the red. Perfectly
