RE: consitintaly peep site tube breaking!
I have never used a peep sight!!! I tried it with my new bow, as I bought a package deal!!!! I took about 10 shots before I removed it!!! No peep, and I still shoot 3" at 35yds! I have never nor will I ever shoot more than 35yds at a deer! One less thing to go wrong!!!!
I do however use a little thread and white out to mark the spot on the string!!
