Brownells Delrin Ring Reducer, 1'' To 3/4''

The Brownells Delrin ring reducer is a straightforward solution when your scope diameter doesn't match your ring size. This 1-inch to 3/4-inch adapter lets you mount a scope with a 1-inch tube into rings designed for 3/4-inch optics, eliminating the need to buy new rings or settle for a scope that doesn't fit your setup. Made from Delrin—a durable polymer that won't scratch or mar your optics—these reducers come as a matched front-and-rear pair, so you get everything needed for a complete installation.

Installation is refreshingly simple. Rather than permanent sleeves, these reducers are split lengthwise and slide on as a drop-in fit over your existing rings. No gunsmithing, no special tools, and no permanent modifications to your gun or mounting system. The matte black finish blends seamlessly with both your scope and rifle, keeping the overall look clean and purposeful.

Whether you're adapting a hand-me-down scope to your current rifle, experimenting with optics before committing to new rings, or building a rig with mixed components, a quality ring reducer keeps your options open. Brownells has been the gunsmith's go-to for decades, and their Delrin reducers reflect that reputation for solid, dependable gear.

Frequently Asked Questions

Will this fit any brand of rings?

The reducers are designed to work with the vast majority of standard ring designs. Since they're a drop-on fit over the outside of the ring, compatibility is broad, but confirm your ring style can accommodate the split-sleeve design.

Is this a permanent modification to my scope?

No. The reducers are removable. Simply slide them off if you need to remount the scope elsewhere or switch back to 1-inch rings.

What's included in the kit?

You receive both the front and rear ring reducers, so you have everything needed to adapt your scope to a smaller ring size.

Can I use just one reducer, or do I need both?

For proper support and alignment, use the matched pair on both the front and rear rings.
