A Brownells rifle aperture peep sight gives you a reliable upgrade or replacement for iron sights on classic or vintage rifles. This 7/8″ × .050″ aperture disc is a straightforward, field-proven aiming solution for hunters and shooters who prefer the speed and simplicity of peep sights over magnified optics. Whether you're restoring a rifle, replacing a damaged sight picture element, or building out iron sight backup, this black aperture fits the bill.
Iron sights have been winning hunting and target matches for more than a century, and there's good reason: they're fast to acquire, reliable in any light, and free from batteries or alignment issues. A quality aperture peep sharpens your sight picture by forcing your eye to naturally center in the disc, which tightens groups and speeds up target transitions. This Brownells aperture is designed to work with Williams Foolproof, Target Foolproof, and 5D sight systems—the standard-shank fit ensures a clean drop-in replacement for matching sights on those platforms.
If you've lost or damaged a peep sight disc, or you're swapping between hunting and target configurations, having the right aperture size on hand keeps you in the field. The .050″ opening strikes a balance between light gathering and sight picture definition, making it a solid choice for mid-range hunting or well-lit range sessions. Black finish resists glare and blends into the sight housing.
| Outer Diameter | 7/8″ |
| Aperture Opening | .050″ |
| Finish | Black |
| Compatible Sight Systems | Williams Foolproof, Target Foolproof, 5D |
This aperture has a standard-length shank and is designed to work with Williams Foolproof, Target Foolproof, and 5D sight systems. If your rifle uses a different peep sight brand or model, verify compatibility before ordering.
The .050″ is the diameter of the hole through which you aim. Smaller apertures tighten your sight picture and improve precision at distance; larger openings gather more light and are faster in dim conditions. This .050″ size offers a practical middle ground for hunting and general rifle shooting.
This is a replacement aperture disc only—not a complete sight assembly. It's intended as a spare or to replace a damaged element on an existing Williams Foolproof, Target Foolproof, or 5D peep sight.
