The TruPeep Max Hunter peep sight from Jim Fletcher Archery is the largest peep sight they make. Why make a peep sight that has a 0.25" hole in it? Simple, on a hunt you may be sitting in a blind, or in a dense forest, or there is just barely any light, and you need as much light as possible to come through so you can clearly see your target and your pin to line up your shot. A great addition to any bow, this peep sight only weighs 8.5 grains, is made of aluminum, and helps create a more consistent sight picture shot after shot. The ingenious design allows perfectly round, shaded hole at full draw, eliminating the need for protruding hoods. String roll and angle not a problem. Safety tie groove keeps peep in place and no tools are needed for installation.
