UTG RMR Mount Set 2 in 1 Combo – Low Profile and Co-Witness in one Set
The correct red dot height does not depend on the red dot itself – but on the weapon underneath it.
The UTG RMR Mount Set 2 in 1 Combo provides two Picatinny heights for RMR-compatible micro red dots: a low-profile solution and a higher co-witness solution.
This set is useful if you not only want to mount a red dot, but also want to select the sight line to match an AR, shotgun, rifle, or training platform.
Why this particular product?
✔ 2 heights in one set
✔ Low profile for flat systems
✔ Co-witness height for AR-like setups
✔ RMR footprint for compatible micro red dots
✔ 6061-T6 aluminum with Torx screws
✔ Useful if multiple platforms are used
Why this product?
The set solves the most common mounting problem with red dots: The optic fits mechanically, but is not at the correct height.
- You can choose between a low and a high sight line
- You are not limited to one platform
- You learn in training which height really suits you
- You can adjust the red dot more precisely to different weapons
10 mm or 22 mm – what fits?
✔ 10 mm: low, useful for shotguns, classic rifles, or flat Picatinny lines
✔ 22 mm: higher, useful for AR setups with co-witness logic
❌ Wrong height: Red dot is mounted, but slow and uncomfortable to use when shouldered
Instructor Tip:
Mount both heights experimentally and shoulder the weapon before zeroing. You'll recognize the correct height when the dot appears immediately in your field of view – without having to search with your head or neck.

Our Assessment
This set is particularly strong for users who have multiple platforms or who want to find out which red dot height really suits their shooting stance.
The low mount is useful when the stock line is low. The higher mount is better suited for AR-like systems with standard sights.
Limitations: It does not replace an optics-ready pistol mount or a special mount for closed systems.
Areas of Application
-
AR/PCC Setups: Test or use co-witness height
-
Shotgun/Rifle: Bring red dot closer to the barrel/rail line
-
Range: Compare heights and optimize shooting stance
-
Multi-platform use: Use one optic with different mounting heights
Features & Operation
- Two separate bases: each mounting height serves a different purpose
- RMR interface: mechanically check compatible optics
- Picatinny clamping: requires a clean, dimensionally accurate rail
- Torx screws: tighten evenly and controlled

FAQ
Why two mounts in the set?
Because different platforms require different sensible red dot heights.
Which height is suitable for AR?
Mostly the higher co-witness variant, if standard sights and head position match.
Which height is suitable for a shotgun or rifle?
Often the low variant, because these weapons usually don't require a high AR sight line.
Does every RMR red dot fit?
Only RMR-compatible optics with the corresponding screw pattern.
Do I have to re-zero after changing?
Yes. Any change in mounting height requires a check of the point of impact.
With the RMR mount set, Picatinny Red Dot and Co-Witness Setup, the chosen mounting height determines whether target acquisition feels quick or artificially forced.
