I haven't used that particular peep, but I do have a peep sight on some guns and they are definitely worth it. The peep on my Lyman extended my range with it from about 75 yards to about 125 yards.
It is an excellent product. I use scopes but when taking trips it is an excellent back up. I have had several scope go south on me while I was taking trips and am using it as back up. I have only shot it enough to sight it in and practice a bit with it but like most Iron sights it is very reliable.
If you can legally hunt with both, it's a great idea.since you can't and if you have a T/C or a Knight, just go with the williams peep, which should work great with the existing front bead on your rifle. there about $38.. Ray
looks to me like a great investment. Like Lee said great back up or for when ya can't use the scope. Looks as though it wouldn't be in the way of other optic's.
