I have come to really like the old T/C model 7194 peep sights and have them on 3 of my Hawken rifles. But they are getting about as rare as hen's teeth and when you do find them they cost quite a few bucks.
I see Williams makes the WGRS peep sight that replaces the rear sight on the rifles. Has anyone ever tried these sights. My concern would be the ability to pick up the aperature that far from the eye unless it is really big.
Any info on these would be appreciated.

The WRGS sight comes standard on the X7. This peep on the rifle i have been using during our muzzle loader season has been reliable. I guess one could write it is 100% reliable; it has never failed. However, it is mounted a way back at the end of the barrel on the X7, and that is where i use it. It works there. There is nothing fancy about it. Adjustments require patience, and attention to detail. There are no 'clicks'. One loosens screws and the sight is 'free'. Time will tell, but as i write this, i may prefer the wgrs to the fp i just mounted on the Extreme, and also on the Dream Season. The wgrs is simply simple.

I have a Williams Peep sight on one traditional rifle. I am not sure of the model of peep. It makes a very accurate rifle though. But I am not a peep sight fan. They just do not work for me in the shadows of a alder/cedar marsh.
