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. Be sure to take off the protective caps first!

Quad rail with 1400 lumen led light, and laser as well. M16 bolt carrier with Giessel trigger. About to add suppresser in the very near future. I'm thinking a 308-rifle suppressed might be more likely to happen.
What I purchased was a Sig Sauer Romeo7 red dot to pair with the RRDM 3X magnifier. Once paired the view was fantastic the magnifier does a real nice job, of producing a magnified view through my new scope. There was nothing left of the target but a few pieces.
