Brownells Delrin Ring Reducer, 30Mm To 1''

The Brownells Delrin Ring Reducer, 30mm to 1" is a practical mounting solution for shooters who need to adapt a 30mm scope to fit into 1-inch diameter scope rings. Whether you're retrofitting an older gun with modern optics or working around ring availability, these reducers slip over your scope's tube and create a snug interface with standard 1-inch rings—no permanent modification to your rifle or scope required.

Made from Delrin, a tough polymer that won't mar or scratch your optic, these reducers are designed to stay out of sight without drawing attention. The matte black finish blends seamlessly with most rifle scopes and won't create glare or reflection. Because they're split in half, installation is straightforward: drop one half onto the front ring and one onto the rear ring, then tighten down normally. No tools, no fussing, no risk of damaging expensive glass.

Brownells ring reducers work across virtually any brand of scope ring—from budget-friendly aluminum to premium steel—as long as the rings accept a 1-inch tube. They're particularly useful if you've inherited a quality 30mm scope but your rifle is set up for 1-inch rings, or if you're building a gun around specific rings you already own. The package includes both front and rear reducer sleeves, so you have everything needed for a complete mount.
