Williams Gun Sight
The Williams Gun Sight Rifle Adj Foolproof receiver sight is a proven, no-frills rear sight option for shooters who want a reliable aiming solution without the weight or complexity of a scope. Built to mount on rifles with factory-drilled and tapped grooved receivers, this adjustable receiver sight delivers the accuracy hunters, sport shooters, and precision rifle enthusiasts have trusted for decades. At just 1½ oz, it won't burden your rifle, and its unobstructed design keeps your field of vision clear—no bulky optics blocking your view of game or target.
What sets the Foolproof design apart is the internal micrometer adjustment system that locks your sight setting in place. Once you dial in your zero, accidental bumps or jostling won't shift your point of aim. That's the kind of dependability that matters in the field, whether you're hunting in dense timber or shooting at the range. The black finish is durable and won't catch light or draw attention during a stalk.
This is old-school engineering that still works: a mechanical rear sight that doesn't require batteries, doesn't fog up, and doesn't need cleaning after a dust storm. If your rifle is already threaded for a receiver sight and you prefer iron sights over glass, or you want a backup to your scoped rifle, the Williams Foolproof delivers straightforward, repeatable accuracy.

The internal micrometer design allows you to dial in your zero, and the locking mechanism secures the adjustment so accidental contact or recoil won't shift your sight picture.
