The z-38 is made in the USA and built to last thanks to it's 6061-T6 Aircraft aluminum construction. Archers can use the same peep sight for years without having to worry about replacing it. Key features that make this peep sight stand out from the crowd include a deep string channel that keeps the peep in place and rock solid for precision shooting shot after shot. Gone are the days of worrying about your peep sight moving at the moment of truth in the woods or on the line at an important tournament. The z-38 has a 38 degree angle at full draw so the peep aligns perfectly with the eye, resulting in effortless shooting. The z-38 is available in 1/8", 3/16" and 1/4" apertures. The edges on the z-38 peep are cleaned and polished, which prevents bow string wear and fraying.
