Description
The Leupold Rifleman Gen 2 1" See-Thru Rings (part #185539) solve a classic rimfire problem: how do you mount a scope without giving up your iron sights? The see-thru design raises your 1-inch optic high enough that you can still drop your cheek and use the open sights right underneath, which is handy for close-range shots, follow-ups, or just when you don't feel like dialing. These are built for rifles with a 3/8-inch grooved receiver, the setup you'll find on most .22 rimfires and a lot of air rifles, so they clamp straight on with no extra base required.
What the Rifleman Gen 2 See-Thru Rings Are Made Of
Leupold machines these rings from lightweight, aircraft-grade aluminum, so you get real strength without piling weight onto a plinker or small-game rifle. The matte black finish cuts glare and blends in nicely with blued barrels and black synthetic stocks. Installation runs on T-15 Torx screws, which seat clean and hold tight. For reference, Leupold spec's the keeper clamp at 14 in-lbs and the ring top screws at 26 in-lbs, so a torque driver makes setup quick and repeatable.
Why the See-Thru Height Matters on a .22
The see-thru channel is the whole point here. Rimfire shooters love being able to keep their factory open sights functional while still having magnified glass ready to go. It's a favorite setup on grooved-receiver classics and bolt guns alike, and folks run these on everything from lever-action rimfires to pellet rifles where that extra vertical clearance is exactly what's needed. Just keep in mind the extra ring height raises your sight line, so you'll want to confirm a comfortable cheek weld with your particular stock.
Dialing In Fit for the Rimfire 3/8" Groove
One thing worth knowing: rimfire dovetail grooves can vary slightly in width from maker to maker, so these fit the vast majority of standard 3/8-inch grooved receivers. If you've got a 1-inch main tube scope and a grooved rimfire, this is a proven, budget-friendly way to get it mounted. And like the rest of the Rifleman Gen 2 line, they're backed by Leupold's lifetime guarantee, which is tough to argue with at this price point.

Frequently Asked Questions
What rifles do the Rifleman Gen 2 see-thru rings fit?
These rings clamp directly onto rifles with a 3/8-inch grooved (dovetail) receiver, which covers most .22 rimfires and a lot of air rifles. No separate base is needed since they attach straight to the groove. Keep in mind rimfire groove widths can vary a little between manufacturers, so they fit the vast majority of standard 3/8-inch receivers.
Can I still use my iron sights with these rings on?
Yes, that's exactly what the see-thru design is built for. The rings raise your 1-inch scope high enough that you can still look through the channel underneath and use your factory open sights. It's a popular setup for quick close-range shots when you don't want to use the scope.
Do these fit a 1-inch or 30mm scope tube?
These are made for scopes with a 1-inch main tube. If your optic has a 30mm tube, you'll want a different ring from the Rifleman Gen 2 line sized for that diameter.
What size driver do I need to install the Rifleman see-thru rings?
The rings use T-15 Torx screws for installation. Leupold spec's the keeper clamp at 14 in-lbs and the ring top screws at 26 in-lbs, so a torque driver helps you tighten them evenly and consistently. A proper torque keeps the scope secure and makes future removal clean.
