Apertures

Q: Which size aperture do I need?
A: Specialty Archery makes 6 sizes of apertures: 1/32” 3/64” 1/16” 3/32” 1/8” 1/4″
We recommend selecting an aperture size that will fit tightly around the scope housing when at full draw. If you are using too large of an aperture, accuracy may suffer due to improper alignment of the scope and peep. If you are using too small an aperture, you may lose some field of view of the scope lens. Using a small aperture will also restrict the amount of light, making for a dim sight picture.

To select aperture size:
if you use a 1 3/8” scope, use the 1/32” or 3/64” aperture
if you use a 1 5/8” or the Pro Series, use the 3/64”, 1/16”, or 3/32” aperture
if you use the Super D or the Pro Series XL, use the 3/32”, 1/8”, or 1/4″ aperture (for these scopes you may also want to consider one of the ¼” peeps)

For hunting, we recommend our ¼” peeps due to the increased light transmission.

Q:What should I do if I notice vibration from the Aperture?
A:If you hear a buzzing sound, this means your Aperture has vibrated loose. First, make sure the Aperture is screwed in tight, but do not over tighten. Use Specialty Archery’s 210078 Dual Hex Wrench. If this does not help, you can put a drop of Vibra-Tite VC 3 (our part VC3), Teflon tape, bow wax, or any other non-permanent binding agent on the threads. This can be found online, or in fastener stores such as Fastenal. Be sure to tighten your Aperture before each use. Bow vibration can loosen the Aperture over time.
