Brownells
The Brownells Rifle 1/2'' X .050'' Aperture Peep is a replacement aperture disc for shooters who need to dial in their sight picture for hunting, target work, or precision shooting. This is the standalone disc component—the part that actually frames your sight picture—sized at 1/2'' diameter with a .050'' aperture opening. If your Williams sight is missing a disc, damaged, or you want to swap apertures for different shooting conditions, this Brownells-supplied replacement gets you back on target without replacing the entire sight assembly.
The .050'' aperture diameter is a versatile middle ground: small enough to sharpen your sight picture and reduce parallax at distance, but open enough for quick target acquisition in lower light or faster-paced hunting scenarios. The black finish keeps glare down and won't catch the eye. This disc uses a standard-length shank, which is the critical compatibility detail—it fits Williams Foolproof, Target Foolproof, and 5D sight models only. Before ordering, verify your Williams sight model to ensure this aperture will install properly.
Whether you're rebuilding a sight that took damage, replacing a lost disc, or experimenting with aperture sizes for different hunting seasons or range conditions, this Brownells peep aperture is a straightforward, economical fix. Keep one or two extras on hand if you shoot Williams sights regularly.
| Aperture Diameter | 1/2'' |
| Aperture Opening | .050'' |
| Shank Length | Standard |
| Finish | Black |
| Manufacturer | Brownells |
This disc with standard-length shank is compatible with Williams Foolproof, Target Foolproof, and 5D sights only. Confirm your sight model before purchase to ensure proper installation.
This is the aperture disc and shank only—the component that installs into your Williams sight base. If your sight base itself is damaged or missing, you'll need to replace the entire sight assembly.
A .050'' opening provides a sharper, more precise sight picture ideal for longer-range or target shooting. Larger apertures allow more light and faster target acquisition but are less precise. The choice depends on your typical shooting distance and lighting conditions.
