Important fit note:

This magnifier is designed for use with the AT3 RD-50 and AT3 LEOS red dot sights. The height of the magnifier is a great match for “absolute cowitness” red dot sights like the AT3 RD-50 with .83″ riser, and also works well with the AT3 LEOS or RD-50 with 1″ riser. To center a red dot in the magnifier’s view, use the adjustment screws on the top and right sides of the magnifier.

Great Set-Up for My 9MM Ruger PC Carbine

I learned many years ago in a funny sounding place, that not all targeting needs to be done by a 16 inch rifle from a battleship. Fact is most of us (IMHO) are probably more than likely going to need something inside 50 - 70 yards with great eye relief and and the advantages of the red-dot. (That is if we ever really need anything). Enter AT3! Putting it all together, the red dot reinforced by the Green laser, and the combination perfectly focused is going to mean real problems for whatever is showing in the glass! The other advantage, of course, is CQB so close you only have time to flip on the laser. Great to know one doesn't have to take time to acquire a normal targeting situation, and may not even need the glass. This is also a great combo for multiple shooters; especially where one has just enough blurriness to need the magnifier, and the other(s) don't.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!

Nice addition

This was a very nice addition to my LEOS red dot. Very easy to get the sight window I want. Five shot groups at 100 yards were 2.6 inches. I’ll take that any day with a 3X magnifier. I do think I can dial it in some. When three shots out of five touch. Hard to beat.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!

Worth the money

I installed AT3 Red Dot with no difficulties, this is a real deal. I found it to make the use of my red dot awesome @ 100 yards

Great magnifier!

This 3x magnifier is definitely the best bang for your buck! The lenses are crystal clear, comes with lens cap and it has enough clearance for my magpul mbus sight to be under it. The mount is really easy to engage/disengage just pull back, move and locks right in. I use it with an RD-50 Pro and I love this setup. For $100 magnifier with a lifetime warranty it cannot be beat!
