Shields RMSw Heavy Duty Reflex Mini Sight with 4 MOA Red Dot$489.99
Availability: In Stock
The Shield RMSw Glass Edition reflex mini sight brings durability and optical clarity to your carry or duty pistol. This 4 MOA red dot is engineered for shooters who demand a rugged, waterproof sight that won't quit in harsh conditions. The Glass Edition pairs a newly designed hard-coated glass lens with an aluminum housing built to Shield's proven RMS footprint—meaning it drops right onto any slide already cut for RMS, RMS-C, SMS, or Jpoint patterns. That compatibility alone opens the door to over 40 mounting solutions across popular handguns, rifles, shotguns, and optic platforms.
Where the RMSw truly sets itself apart is waterproofing. Gasket-sealed construction keeps moisture out without the need for add-on plates, and when mounted correctly, the sight remains watertight to 20 meters for over 30 minutes. The redesigned frame adds housing thickness and a refined side profile that lets you co-witness with standard iron sights—a practical advantage for pistol shooters who value backup aiming options. One CR2032 lithium battery powers the dot, and the electronics include upgraded battery contacts for reliable performance. The glass lens is specifically engineered to resist scratching while maintaining the crystal-clear view shooters expect from a quality reflex sight. Night vision compatibility rounds out the feature set for tactical flexibility.
A note on installation: the RMSw's full waterproof rating depends on a tight seal between sight and mounting surface. Single-stack and tapered-top pistol frames may not achieve the same watertight integrity, so verify compatibility with your platform before mounting.
