Description
The Trijicon RMR Type 2 LED RM01 with RM33 is the simplest LED version of Trijicon’s RMR: a 3.25 MOA red dot with automatic brightness and no buttons, paired with the low RM33 Picatinny mount. It is built for users who want a rugged dot that just works without menus.

Trijicon RMR Type 2 LED RM01 with RM33 Overview
Trijicon part RM01-C-700601 uses the Type 2 RMR housing in matte black forged aluminum. Instead of push-button brightness control, the RM01 uses a light sensor that automatically matches dot brightness to ambient conditions. That makes it a straightforward choice for duty, home defense and shotgun use, where the fewer controls there are, the fewer things there are to get wrong.
Choosing the 3.25 MOA Dot
The 3.25 MOA dot is the most popular RMR configuration because it balances speed and precision. It covers under an inch at 25 yards, small enough for accurate shots on a pistol and fine enough for rifle offset use, yet still quick to find during the draw. If you are buying one RMR for general use, this is usually the size to choose.

Controls and Battery
This LED model uses automatic brightness, with a sensor that adjusts the dot to ambient light. There are no buttons to manage, which keeps the design simple for duty use. Trijicon rates the battery for years of continuous use, and the battery is replaced from the bottom, which means removing the sight and confirming zero afterward.
Mounting Options
This package includes Trijicon’s RM33 Picatinny rail mount, a low mount that puts the RMR close to the rail. It suits shotguns, rimfires and use as a low reflex sight on carbines, and it lets you run the RMR on a rail-equipped gun right out of the box.

Built for Abuse
The RMR is famous for durability. Its forged aluminum body uses a patented housing shape that steers impact energy away from the lens, and the sight is waterproof to 66 feet. Windage and elevation adjust 1 MOA per click with no special tools needed. This model wears Trijicon’s standard matte black anodized finish, which matches most pistol slides and rifle receivers and shows wear less than colored coatings.
Honest Considerations
Because brightness is fully automatic, you cannot crank the dot up or down yourself, which some shooters miss when the gun is in shade and the target is in bright light, or when using night vision. The adjustable LED models (RM06, RM07, RM09) solve that at a higher price. The low mount suits shotguns and low rails more than AR-15s.
Ordering and Transfer
When you order a firearm from MAG5 Firearms, we ship it to the licensed dealer you choose. Your dealer completes the ATF Form 4473 and the background check, and may charge a transfer fee. Local buyers can complete the transfer at our shop. Bring a valid ID, and check your state waiting period before you plan a hunt or a range trip.
Safe Storage
Store the firearm unloaded in a locked safe or case, with ammunition kept separately. A cable lock or trigger lock is a good backup, especially in a home with children or visitors. Keep the original box and paperwork, and record the serial number in a safe place in case the gun is ever lost or stolen.
