The Weaver #28 Top Mount Base is a lightweight aluminum scope base engineered for shooters who demand reliable optics mounting without unnecessary weight. This gloss-finished base mounts directly to the top of receiver surfaces, making it a straightforward choice for hunters, long-range shooters, and precision rifle builders working with modern and vintage firearms alike. Unlike universal rail systems, a purpose-designed Weaver base gives you a solid, repeatable platform for your optic—whether you're setting up a hunting rifle, a target gun, or a long-range handgun.
Weaver bases are built from durable aluminum that resists corrosion while keeping your rifle balanced and nimble. The gloss finish provides a clean aesthetic and won't snag slings or brush. Because scope base selection is rifle-model-specific, confirm that the #28 is the correct fit for your firearm before ordering—Weaver makes over 50 different models (numbered #68 through #604) to match specific actions and receivers, and using the wrong base can compromise both accuracy and safety.
Sold individually, so if you're mounting a scope, you'll need both a front and rear base (or a base pair set, where available for your model). This separation lets you order exactly what your rifle needs without paying for extras. Once installed and properly torqued, a Weaver base provides the stable foundation your optic needs to hold zero through hunting seasons, competition days, or range sessions.

Frequently Asked Questions
Is the #28 base compatible with my rifle?
Weaver bases are rifle-model-specific. The #28 fits certain modern and older rifle actions, shotguns, and long-range handguns, but you'll need to verify compatibility with your exact firearm before ordering. Weaver offers over 50 different base models (#68 through #604) to match specific receivers and actions, so double-check your rifle's specifications to ensure the #28 is the correct choice.
Do I need to buy one base or two?
Scope bases require both front and rear mounts to properly support your optic. This base is sold individually, so you'll order it twice—once for the front and once for the rear—unless a base pair set is available for your rifle model. Some rifles do offer matched pair options, so check if one exists for your gun.
What's the difference between the #28 and other Weaver base numbers?
Weaver bases are numbered and engineered to fit specific rifle actions and receiver designs. The #28 is designed for particular firearm models; other numbers (#68 through #604) fit different actions, calibers, and platforms. Selecting the wrong number will result in poor fit and potential accuracy or safety issues.
Can I use this base on a shotgun or long-range handgun?
Yes—the #28 is designed to work on shotguns and long-range handguns as well as rifles, but again, fitment depends on the specific model. Verify compatibility before purchase.
