Description
Ultra-low mounting plate for direct attachment of a red-dot sight to the barrel/upper on the Ruger Mark series.
By eliminating the extra height from a rail and adapter plate, you get a significantly lower, cleaner, and more streamlined setup with the sight position closer to the bore — among the lowest on the market.
Key Features
- Ultra-low profile: only 1 mm (RMR) or 2 mm (other footprints) thick — less than half the thickness of most alternatives
- Mounts directly to the barrel (non-reciprocating)
- Alignment pins that keep the red-dot securely in place and maintain zero
- Made in the USA from durable, lightweight PA12 nylon
- Quick and easy installation
- Holds zero well even with high round counts
Compatibility
Fits Ruger Mark I, II, III, and IV models with factory threaded holes on top of the upper.
Not compatible with Mark IV 22/45 Tactical Silencer Shop Exclusive (SSH) models.
Compatible with TacSol Pac-Lite uppers (note that these use #6-40 threads instead of #6-48 — separate screws are required).
