I used that peep sight for a couple years on a Renegade. It is an excellent peep sight. I took it off a while back for a couple reasons. First is I would not remove the center in low light and found it hard to site on deer with it. Now granted the center does come off and it makes a ghost ring that opens the sight picture up considerably. I just would not do it. My luck, I'd of lost that center piece between my stand and home. That is just the way things go for me.
On the range in the day time, it is hard to find a better sight unless you go optics. The sight is easy to use, and very accurate. I still have it here around the house.The longest shot I ever made with a muzzleloader (80 yards) was with that peep sight. I hit exactly where I was aiming. I guess I should throw it on something.
If the rifle you are going to put it on is a Renegade or Hawkins then it is a very good selection. I went to 1x scopes instead. If it is a Lyman rifle, they are pre tapped in many cases for the Lyman Peep sight.
