The Holosun HM3XT quick-detach 3x magnifier for absolute and 1/3 height optics in titanium pairs with a compatible red dot to extend engagement distance without swapping optics, using a flip-to-side design for instant transitions back to 1x. Holosun builds the housing from titanium and rates it IP67 waterproof, and both a QD mount and spacer ship included so the magnifier works with absolute or lower 1/3 co-witness height optics. At 9.8 ounces the magnifier delivers a 37-foot field of view at 100 yards with 2.75 inches of eye relief. Among quick-detach sight magnifiers, this configuration favors shooters who want maximum durability from a titanium build.
