Model 3XP is designed to be used with our full range of tactical optics; the EG1, FC1, RV1 and RV2. Precise adjustment of elevation and azimuth centers the red dot in your field of view. The 3XP magnifier significantly improves accuracy on medium and long range targets, and it enhances target identification. Its machined aluminum-alloy housing, multi-layer coated lenses, and superior waterproofing make the 3XP far more rugged than other magnifiers.
