The Weaver #423 top mount rifle scope base is a single-piece aluminum mounting solution built for shooters who want simplicity and reliability without the fuss. Whether you're building a hunting rifle, setting up a range gun, or mounting glass on a shotgun or long-range handgun, this one-piece base keeps your optic centered and stable. Cast from lightweight aluminum, it's engineered to handle the recoil and vibration of live fire while keeping your point of impact true shot after shot.
One-piece bases lock your scope directly to your rifle's receiver in a single rigid platform—no front-and-rear alignment headaches, no stacking tolerances. That simplicity matters when you're afield or at the range and need to trust your setup. The matte finish resists glare and blends cleanly into most rifle profiles without drawing light or attention.
Weaver #423 bases fit a broad range of rifles, shotguns, and handguns, both modern platforms and vintage iron. Because this is a single-piece design, verify the #423 fits your specific rifle model before ordering. If your rifle requires both front and rear bases, note that this base is sold individually—you'll need to order the matching pair for your setup. Weaver also offers matched two-base sets for certain models if you prefer a coordinated system, so check compatibility for your gun.
