Firearms are loaded with tight corners and tiny parts, which makes working or building guns a pain at times. Make sure you can see your work clearly with the iGaging 10X Magnifier. Each magnifying loupe is equipped with eight LED bulbs, so small components and dark firearm internals are instantly flooded with illumination, providing all the information users need to keep their project going. The unit's lens won't distort the details on your gun, and a built-in reticle allows users to measure length, diameter, radii, angles, pitch and thickness. When not in use, the loupe can be protected with the included leather case. Mfg: Igaging
