Midwest MK2 30MM RMR Cap$64.95
Availability: In Stock
The Midwest Industries MK2 30mm Railed Cap is a precision-machined quick-detach optic cover engineered for shooters running co-witnessed backup red dots or backup sights on railed scope mounts. Built from hard-coat anodized 6061 aluminum, this cap protects your secondary optic while staying out of the way during target acquisition—and critically, it's designed to return to zero reliably if you need to deploy your backup sight when your primary scope is down.
Midwest Industries machined this cap to work across current and previous generations of their scope mount ecosystem, so compatibility is straightforward if you're already running their rails. The top surface is precision-engraved with torque specifications, a small detail that makes setup faster and more consistent in the field. Since this is a cap for railed mounts, it's equally useful whether you're building a precision long-range rig, a tactical carbine, or a hunting setup where a secondary aiming solution adds confidence.
Made in the USA and backed by a lifetime warranty, the MK2 cap is the kind of forgotten detail that separates a half-built optics setup from a complete one. Whether you're protecting a milled mounting surface, keeping dust out, or just leaving the cap on a railed mount you're not actively using, this is honest American manufacturing at work.

The MK2 cap is designed to fit current and previous generation Midwest Industries scope mounts with railed surfaces. If you're using Midwest rails or railed scope rings, this cap should fit. For specific mount compatibility, reference your mount's documentation or contact us.
This cap is designed to protect railed mounting surfaces when no optic is installed, or to cover the rail when you're not using a secondary sight. It's not designed to co-house a mounted optic; it covers the rail itself. Note that if your primary scope has taller turrets, they may limit how the cap sits when covering the rail surface.
The MK2 cap is precision-machined for repeatability, meaning it's designed to return to zero if removed and reinstalled—critical for a backup cap you might need to remove and deploy a secondary sight. This precision machining is part of why shooters trust Midwest Industries products in precision setups.
You receive the MK2 30mm railed cap. Torque specifications are engraved on the top to guide installation.
