Kit includes: Hooded 1/4" Peep, Cable Key, Silicone Alignment Tubing, Peep Reducer, and a Dual Aperture Wrench. The revolutionary Super Hunter Peep uses optional 1/8" apertures with 5 hole sizes to choose from (1/32, 3/64, 1/16, 3/32, and 1/8) for a bright view. The optional screw-in Verifier lenses sharpen the pins. The optional Clarifiers when used with a scope and lens sharpen the target face. The Super Ball Peep is designed to accept all of the Super Peep apertures, clarifiers, and Verifiers. Use of the 753-3 Peep Adapter is necessary for the 1/8" verifiers, apertures and clarifiers to fit the 1/4" peep. The 1/4" verifiers will screw directly into the peep. Use of optional 210078 dual hex wrench is recommended for insertion of verifiers, clarifiers, and apertures. The Super Hunter Peep is available in 37 degree string angle groove.
