Can the No-Peep be used with a HHA style sliding single-pin sight? I'm curious about this, but don't want to drop $35 for something that won't work with my setup.
Yes it can be used with sliding single pin sights.
When I first started using the No-Peep I had an HHA single pinsight on my bow and did not get any obstruction at all.
I usually set my no peeps up so they are above the pin guard and behind the riser.
