The Specialty Archery Apertures will screw directly into all Specialty Archery Peeps with use of the Dual Aperture Wrench (210078). You will need a peep reducer (753-3, sold separately) for the apertures to fit into the 749-37L and 749-37LH peeps.

Available in 5 sizes: 1/8", 3/32" 1/16", 3/64", 1/32"

To determine correct aperture size:
If you use a 1 3/8”, True Spot Target, or Versa scope, try the 1/32”, 3/64”, or 1/16” aperture.
If you use a 1 5/8” or the Pro Series scope, try the 3/64”, 1/16”, or 3/32” aperture.
If you use the Super D, Pro Series XL, or True Spot 3D scope, use the 3/32” or 1/8” apertures.
NOTE: for these larger scopes you may also want to consider one of the larger ¼” peep housings.
