The Brownells Rifle 3/8'' X .050'' Aperture Peep is a precision replacement sight disc engineered for shooters who need to swap out a damaged, lost, or worn aperture on their existing Williams-compatible rear sight. Whether you're running a classic hunting rifle or setting up a target rig, having the right peep aperture on hand keeps you in the field or on the line without downtime. This black aperture fits standard-length shanks on Williams Foolproof, Target Foolproof, and 5D sights—the industry workhorse rear sights trusted by hunters and precision shooters for decades.
Peep sights remain one of the most reliable aiming systems for hunting and marksmanship, offering a natural sight picture that helps shooters achieve fast, accurate aim in variable light. The 0.050'' aperture diameter is a versatile mid-range opening, suitable for general hunting, field shooting, and tactical training where you need a balance between light gathering and precision. Because peep sights let the shooter's natural eye alignment do the work, you get consistency without complex adjustment—ideal when you're moving between different shooting positions or conditions.
If you already own a Williams-equipped rifle, keeping spare apertures in your shooting bag or truck makes sense. A broken or lost disc shouldn't force you to buy an entire new sight assembly. This Brownells replacement is a straightforward solution: install it, zero your rifle, and get back to work.
