If you put a peep sight on your rifle make sure the front sight is fiber optic. Otherwise they are very hard to find in low light (dawn, dusk, and shadows) conditions. I have a peep site on my T/C Renegade. It is a great site in the right lighting conditions. At 100 yards even with my eye sight, I can still group them very well. I had a gunsmith drill my front sight and put florsecent white paint in it so it stands out like a sore thumb.

If your peep is adjustible with the size of the hole as mine is. Practice with it both ways. I can screw the peep out and it opens the rear peep much bigger, but again, it changes the site picture.

My new rifles came with the fiber optic sites and I think I am going to leave them. So far I kind of like them.
