Hey Bowman; welcome to the forum and check the link that greyhawk listed, that peep sight is a" Williams" from Midwayusa.com @ $30+ bucks it goes right in the scope mount holes and I had to change the front sight as well, a Williams gold bead (1/16") .406" height I believe, also midway $12-$15 bucks. I'm getting 4" groups @ 100 yards. That rifle will print 2" groups with a scope.
