Description
The Talley RMSC-1022 is a direct optic base built to put a Shield RMSc footprint red dot right onto the factory tapped holes of a Ruger 10/22 receiver. Instead of running a Picatinny rail and then bolting an optic on top, this base skips the middleman. You get a lower mounting height, a cleaner look, and one less connection point that can work loose over time. For folks setting up a plinker, a truck gun, or a small game rig with a compact dot, it's a tidy way to go.
What Makes the RMSC-1022 Base Different
Talley has been making American-made mounts for decades, and this piece carries that reputation. It's CNC-machined from aircraft-grade aluminum with a matte black anodized finish, so it holds up to handling and weather without adding meaningful weight to a rifle that's known for being light and handy in the first place. Because it's purpose-cut for the RMSc footprint, there's no adapter plate sandwich to stack tolerances and raise your optic higher than it needs to be.
Optics That Fit the Talley RMSC-1022
This base accepts red dots built on the Shield RMSc footprint. That covers a wide range of popular compact and micro reflex sights including the Shield RMSc line, SIG Romeo Zero, Holosun 407K and 507K (which use the closely related K footprint), Vortex Defender CCW, and similar RMSc-pattern optics. If your dot was designed for an RMSc-cut pistol slide, odds are good it bolts right onto this base.
Getting the RMSC-1022 Mounted on Your 10/22
Installation is straightforward on a standard Ruger 10/22 with the factory threaded holes in the receiver. Clear the rifle, pull any existing rail or mount, line the base up with the receiver holes, and snug it down. A little thread locker and proper torque will keep everything locked in through plenty of rounds. From there you add your optic, zero it, and you're out the door with a low, fast-pointing rimfire setup.

Frequently Asked Questions
What optics work with the Talley RMSC-1022 base?
It's cut for the Shield RMSc footprint, so it fits a broad range of compact and micro reflex sights built on that pattern. That includes the Shield RMSc, SIG Romeo Zero, Holosun 407K and 507K on the closely related K footprint, Vortex Defender CCW, and similar RMSc-pattern dots. If your optic was made for an RMSc-cut pistol slide, it should bolt onto this base.
Will the RMSC-1022 fit any Ruger 10/22?
It's designed for Ruger 10/22 series rifles that have the standard threaded holes on top of the receiver. If your rifle currently wears a factory rail or a separate mount, you remove that first and attach this base in its place. Rifles with a permanently integrated, non-removable rail would not use this type of base.
Why use a direct base instead of a Picatinny rail and adapter?
A direct base mounts your red dot lower and removes an extra connection point in the stack. Less height means a more natural cheek weld and a sight picture that lines up quickly, and fewer joints means fewer things that can shift under repeated firing. For a compact RMSc dot, it keeps the whole setup clean and purpose-built.
Is the Talley RMSC-1022 made in the USA?
Yes. Talley manufactures its mounting products in America and has a long-standing reputation for well-built, reliable bases and rings. This base is CNC-machined from aircraft-grade aluminum with a matte black anodized finish.
