Thanks chap, It really did'nt cost me anything as I had some gift cards to burn from the holidays. The ones I got had a rear interchangable peep that you could swith out so you look through a circle peep with fibers and line up the front fiber. I have never seen fibers so bright before and I am thinking about buying another set for my other guns. I always scope my guns but two years ago I shot a doe at 5 yards and had to use my open sights, luckily I have my scopes mounted high so I can see under in case they come in close.
