One of the most advanced tree sight available this aluminum sight features a dual sighting system on a compact machined frame that places the sights about seven inches apart. The Original rear sight is paired with TroGlo's Tru-Site Xtreme, small diameter pin head assembly. The glow in the dark shooters ring makes targetting easy even in low lights.  As a bonus, the Violet LED lighting reduces pin glare. When taking aim, the shooters ring will encircle the rear sight ring perfectly for a concentrated secondary point of alignment. The sight also has extra long protected fibers (.029) and dual pin rails for precision pin alignment.
