I just got the ghost ring truglo sight to replace stock sights. The gun shot really good with them. I put 20 rounds of 240 grain XTP hornady with 80 grain ff777 and put together some really tight groups on saturday (for me). Best my winchestor x-150 (actually cva) has ever shot. I also modified the cheap stock that was rubbing on the barrel and free floated it. I don't know what exactly it was that put together the nice groups but it sure shot way better than it did the week before with 405 powerbelts and stock sights. If I was a better shot I think I could have put 3 under 1" at 50.
I'm still interested in the williams peep anyone had experience with both these sights?
