RE: 5/32 inch peep?
See if I can get this right. Specialty Archery Super Peep/3D kit. The peep itself is 1/4", threaded for different inserts they make. The kit has inserts from about 3/64" on the small side up to 3/16". Use no insert and you have a hole 1/4". This is what I use on my hunting bow, smaller inserts for 3D and targets. This is a no-tube peep.
They also make one with a tube that is larger, but still takes the inserts.
Does this help?
