Learn how to sight in your RMR Type 2 3.25 MOA and care for its battery with a simple step-by-step process that avoids common mistakes.
Quick answer
Zero your RMR Type 2 3.25 MOA from a steady rest at 25 yards, then confirm at 10 yards, and replace the CR2032 battery annually or when the dot dims—using the audible clicks to fine-tune windage and elevation.
Why the 3.25 MOA dot changes your zeroing approach
The 3.25 MOA dot covers about 0.8 inches at 25 yards, so it is small enough for precise aiming but large enough to see quickly. That size makes it a good fit for both close-range and mid-range work, but it also means you need a stable rest to avoid chasing the dot during adjustment.
If you are used to larger dots, you may find the 3.25 MOA reticle less forgiving when shooting offhand. Use a bench rest or sandbags for initial zeroing to keep your groups tight and your adjustments meaningful.
Battery life and adjustment trade-offs
The RMR Type 2 Adjustable runs on a single CR2032 battery, and the eight brightness settings let you match conditions. Higher brightness settings drain the battery faster, so reserve the brightest settings for bright daylight and use lower settings indoors or at dusk.
The audible clicks on the adjustment screws give you tactile feedback, but they do not tell you how far each click moves the point of impact. You must confirm each change on paper—do not assume a click value.
Step-by-step: sighting in and battery care
- Mount and confirm fit: Ensure the RMR is securely mounted to your pistol or rifle according to the manufacturer's instructions. Use a torque wrench if available and apply threadlocker to the screws. Common mistake: over-tightening the screws, which can damage the aluminum housing or strip threads. Check that the optic does not shift when you push on it—any movement means you need to re-mount before zeroing.
- Set initial brightness: Turn the RMR on and set it to a middle brightness setting (around 4 or 5). You want the dot visible but not blooming. Common mistake: using the brightest setting indoors, which wastes battery and makes the dot appear larger than its true 3.25 MOA size. Adjust brightness until the dot is a crisp point, not a starburst.
- Fire a confirmation group: From a steady rest at 25 yards, fire a five-shot group at a clean target. Take your time and focus on the dot, not the target. Common mistake: rushing the group or using a rest that allows the pistol to move. If your group is wider than 2 inches, fix your rest or technique before adjusting the optic.
- Adjust windage and elevation: Using the adjustment screws (follow the arrow directions on the optic), make small changes—typically 1-2 clicks at a time. Fire another group after each adjustment. Common mistake: making large adjustments without confirming impact, which leads to overshooting the zero. Keep a log of clicks and group locations to track your progress.
- Confirm at a closer distance: Once zeroed at 25 yards, move to 10 yards and fire a group. The point of impact should be close to your point of aim, though some offset is normal. Common mistake: re-zeroing at the closer distance, which ruins your 25-yard zero. Note the offset at 10 yards for reference—do not adjust the optic.
- Replace the battery proactively: Replace the CR2032 battery annually, or sooner if the dot dims or flickers. Use a high-quality battery and follow the manufacturer's instructions for battery replacement. Common mistake: waiting until the dot fails during a critical moment. Mark the installation date on the battery or in your calendar.
- Store and maintain: Store the RMR with the battery removed if it will sit unused for months, and clean the lens with a microfiber cloth. Avoid harsh solvents. Common mistake: leaving the battery in a stored optic, risking leakage. Do a quick function check (dot brightness and adjustment clicks) before each use.
