Trijicon RMR® Type 2 Red Dot Sight

Last reviewed: 2026-04-18 by Jake Terry, FFL07/SOT3, competitive shooter.

The Trijicon RMR Type 2 red dot sight delivers a 3.25 MOA dot, adjustable LED illumination, and a housing engineered to survive slide-ride recoil on semi-automatic pistols. Built for law enforcement, concealed carry, and competition, the RMR Type 2 offers manual and automatic brightness modes — manual holds for 16.5 hours before reverting to auto, ensuring the optic is mission-ready without draining the battery during storage. Trijicon machines the Type 2 body from forged 7075-T6 aluminum, then applies a patented housing geometry that redirects impact stress away from the lens. You get a reflex sight proven on Glock MOS, Springfield OSP, and aftermarket milled slides.

Glass & Internals

The RMR Type 2 uses a single CR2032 battery, side-mounted brightness buttons, and an ambient light sensor for automatic mode. The 3.25 MOA dot spans enough screen real estate for fast acquisition inside 7 yards, yet remains fine enough for 25-yard precision work. Night-vision compatibility extends from setting 1 through setting 4; settings 5–8 cover daylight conditions. Button lockout prevents inadvertent mode changes during holster draws or rough handling. The Type 2 shares the mounting footprint of the original RMR Type 1, so existing adapter plates and direct-mill cuts remain compatible. Factory spec calls for a 4-year battery life on setting 4 in automatic mode — field reports confirm 3+ years of daily carry without a swap.

Technical Breakdown

Trijicon ships the RMR Type 2 with a battery, lens cloth, and adjustment tool. Glock MOS, Springfield OSP, Walther PDP, and H&K VP9 Optics Ready pistols require Trijicon mounting kit AC32064 (sold separately) to achieve proper plate height and screw length. Direct-milled slides from agency armorers or aftermarket shops accept the RMR without adapters. Browse related pistol optics in our Trijicon RMR collection.

Matching It to Your Build

The 3.25 MOA dot balances speed and precision across pistol, PCC, and scout-rifle applications. Concealed-carry practitioners favor the Type 2 for one-handed slide racking without knocking the optic offline; competition shooters value the button lockout during stage movement. The RMR Type 2 survives +P and +P+ defensive loads, 10mm hunting rounds, and prolonged strings of rapid fire without zero shift. If you run night-vision devices, settings 1–4 prevent bloom while maintaining enough brightness for passive aiming. Hunters mounting the RMR on a carbine or shotgun gain fast target acquisition in timber or brush, though magnified optics remain the better choice beyond 100 yards.
