My reply is much different than those posted before me. I have used the Marbles peep and their Improved Peep sight ... had problems with both... Marble's sights have a tendacy to toggle or move. I shoot at 200 yards and if the tang sight moves any you are out of luck at hitting the target. I tried the Taylor's and Co., DOS 2 sight which is a copy of the orginal Winchester sight, but it is worthless also as far as accuracy, looks good, but that is about all. I tried a couple of Italian made Tang Sights and gave up. The Marble's company did respond well when I told them of the problem, they replaced their sights at no charge for me. But I still was not happy with them. I finally forked out the green and went with Kelly Sights. Best decision I have made in regards to Long Range Shooting. Kelly Sights are accurate and they also look good on the rifle. I first ordered the Kelly for my '86 Winchester (Chiappa) and I will be ordering one for my 45-60's also. Here some pics of the Kelly Sight on my '86.
