Bear Encounter peep sight size

I need to know how big the wheel peep sight on the RTH Encounter is. I want to get a smaller one because I can see around my entire sight.

I appreciate your help towards this request.
Best Regards.

 

I've never measured it but my guess would be 1/4"... If it were me, I'd ditch their stock peep and try a regular style 3/16" peep...

Something like: RAD Super-Deuce 38 Peep 3/16" 38 degree (<37" Axle length) Red

 

Thx a bunch Sir, I will follow your tip
