I installed it first with my peep still on but once you get it where you want it..TAKE THE PEEP OFF.. because I was trying to wean myself off the peep and onto the no peep..doesnt work..I had to jump in and do it all at once b/c I was relying on the peep and not the nopeep...no I couldnt imagine not having one..besides makes your bow a little faster too
