Vector Optics MOS‑to‑MAG RMS Footprint Steel Adapter SCFRM‑16 – Rugged Optic Mount for Glock® MOS Pistols
The Vector Optics SCFRM‑16 MOS‑to‑MAG RMS Steel Adapter is a precision-engineered accessory designed for Glock® pistols with MOS plates. This adapter converts the MOS footprint to the MAG footprint (compatible with RMS), allowing popular red dot reflex sights to be mounted securely on your handgun.
Key Features & Benefits
- RMS Footprint Compatibility: Enables installation of MAG‑format optics (RMS‑compatible) on Glock® MOS-equipped pistols.
- Steel Construction (#45 Steel): Ninja-level durability with superior rigidity and recoil resistance.
- Ultra-Low Profile: Just 6.3 mm (0.25 in) height keeps the optic close to the bore axis—ideal for co-witness setups.
- Precision CNC Machined: Ensures tight tolerances, perfect alignment, and consistent zero retention.
- Lightweight: Only ~18.5 g (0.65 oz) without optics, offering minimal added mass to your handgun.

Construction & Compatibility
Machined from high-grade #45 steel, this adapter provides unmatched durability and shift‑free zero retention under recoil. Its low-profile footprint ensures your optic stays close to the pistol’s slide, maintaining realistic sight alignment and minimizing slide mass increase. It's ideal for mounting MAG‑format dots such as those with RMS footprint on Glock MOS‑equipped pistols.
Installation & Usage
Installation is straightforward: remove factory MOS plate from your Glock slide, align adapter and preload screws, then mount your MAG‑format red dot optic with proper torque. Use the included Torx screws (two M3×6 and two M3×8) for both slide mounting and optic attachment. Zero retention remains secure through repeated use.
Ideal Use Cases
This adapter is perfect for US practical shooting, law enforcement, or concealed‑carry setups where Glock MOS platform pistols are equipped with compact MAG/RMS red dots. Its low height and steel build reduce creep and maintain optic integrity in demanding environments.
Summary
The Vector Optics SCFRM‑16 MOS‑to‑MAG Steel Adapter seamlessly bridges Glock MOS systems and MAG (RMS‑compatible) red dot footprints. If you're mounting RMS-format optics like DeltaPoint Pro clones or MAG-type off‑brand models to a Glock MOS, this precision steel adapter offers secure fit, minimal elevation change, and battlefield-grade durability.
