The Midwest Industries MI-MK2-RMRL is the "Low" profile variant of the newly released MK2 Series non-QD optic mounts. Launched in early 2026, the MK2 line updates Midwest's classic mounts with refined aesthetics, precision engraving, and 4140 heat-treated steel clamps for maximum holding strength.
Product Specifications
- Mount Height: Low (Designed for use on shotguns, AKs, or subcompact platforms where a co-witness with iron sights is desired).
- Footprint: Trijicon RMR (Also fits SRO, Holosun 407C/507C/508T, and other RMR-pattern optics).
- Material: 6061 Aluminum with a Hard Coat Anodized finish.
- Clamping System: Non-QD, using robust Torx hardware for a set-it-and-forget-it installation.
Key MK2 Improvements
Compared to the older MI-RMR-L models, the MK2 series introduces several "hard-use" upgrades:
- Steel Clamping: Uses heat-treated 4140 steel clamps rather than aluminum, which significantly reduces the risk of the mount shifting under heavy recoil or impact.
- Return-to-Zero: Precision machining ensures that if you remove the mount and re-install it in the same rail slot using the same torque, your zero remains remarkably consistent.
- Tactile Edge: The MK2 features smoother, more radiused edges to prevent snagging on gear or "coining" (damaging) your picatinny rail.
Compatibility & Mounting
| Platform | Use Case |
| AR-15 | Ideal for a 45-degree offset mount or as a primary optic on a high-comb stock. Too low for a primary optic on a standard flat-top AR without a riser. |
| AK-47/74 | Perfect for use on a railed gas tube (like the Ultimak) or a side-rail mount to maintain a slim profile. |
| Shotguns | The preferred height for Mossberg or Remington receivers to keep your cheek weld natural. |
