Special Features
The fully enclosed emitter seals the LED and optics inside the housing, blocking dust, carbon fouling, debris, and moisture from reaching the emitter regardless of carry environment or field conditions.
The patented RMR-inspired impact-diverting housing shape redirects impact force away from the lens, enabling one-handed slide manipulation on a flat surface without risking damage to the optic.
The top-load CR2032 battery compartment allows a swap without removing the sight from the slide, keeping mount torque and zero intact between every battery change with no tools required.
Ruggedized battery contacts and hardened internal electronics protect performance in the most demanding duty and field environments.
Practical Benefits
The RMR footprint mounts directly to every existing RMR-cut slide and compatible direct mounts without new plates, dovetails, or adapters, making the RCR the only fully enclosed pistol optic that fits your existing slide cut and duty holster setup.
The 6-year battery life at setting 5 eliminates battery anxiety on a duty or carry pistol, delivering years of reliable runtime without tracking usage hours or carrying spare cells.
Your 3300001 gives you Trijicon’s lifetime-guaranteed, American-made enclosed emitter design on the most widely supported pistol footprint in the industry, built to the same durability standard as the legendary ACOG.
The Trijicon RCR Enclosed Red Dot Sight (3300001) with its 3.25 MOA red dot is a proven choice for law enforcement, military, and duty pistol users who want a fully enclosed, American-made red dot on their existing RMR-cut slide without changing their holster or mount hardware.
