Leupold 184809 Open Range Dovetail Black Aluminum Rimfire Rifle 1 Piece
$46.20
The Leupold Open Range rimfire scope base brings solid, no-gunsmithing mounting to your .22 rifle without requiring drilling or tapping. Built as a one-piece aluminum base in black, it's engineered specifically for rimfire rifles wearing 11mm or 3/8" dovetail rails — the standard found on most .22s, from basic plinkers to dedicated target guns. If you're setting up a new rimfire or swapping scopes on an existing rifle, this base saves you a trip to the gunsmith and keeps your receiver untouched.
Leupold's Open Range line has earned trust among rimfire shooters who want straightforward, reliable scope mounting without fuss or expense. The one-piece design is rigid and repeatable, meaning your zero stays put between shooting sessions. Because it accepts any standard cross-slot ring, you have complete freedom to pair it with the rings that suit your scope tube diameter and shooting style.
Rimfire hunting, plinking, and competition shooting all demand accuracy and repeatability — and the foundation matters. This base delivers both without the cost or hassle of permanent modification to your rifle.

Frequently Asked Questions
Will this base fit my rimfire rifle?
This base is designed for .22 rimfire rifles with 11mm or 3/8" dovetail rails. Check your rifle's receiver to confirm which standard it uses — both are common on rimfire platforms. If you're unsure, photos or your rifle's manual can clarify.
Do I need a gunsmith to install it?
No. The dovetail design mounts directly to your rifle's existing rail without drilling, tapping, or permanent modification. Installation is a field task any shooter can handle.
What rings work with this base?
The base accepts any standard cross-slot rings. You can choose the ring height and diameter that match your scope and your rifle's profile.
What scope sizes can I use?
The base itself accepts any cross-slot ring size, so compatibility depends on your chosen rings and scope tube diameter — typically 1 inch for rimfire applications, though confirm your scope's specs.
