You can't go wrong with Williams. They're better than a rear buckhorn if you have aging eyes. They're unobtrusive. Rugged. And just look right. Here's one on my 336 .35 Remington.
10Glocks, what's the model of that Williams? Not sure why, but I've never seen one which mounts to the top of the receiver on a 336, only the type that go through the side. I like the look of that setup.
