Find your target quickly with a 3 MOA reticle
The MRM Red Dot features a 3 MOA red reticle, which allows you to locate targets quickly during dynamic airsoft matches. Thanks to the unlimited eye relief, you maintain a comfortable field of view from virtually any shooting position.
The brightness of the aiming point can be easily adjusted using the large rubber control knobs.

The casing is made from high-quality polymer, meaning the visor weighs just 50 grams. This ensures the replica remains well-balanced, whilst its robust construction can withstand intensive use on the playing field.
In addition, the Red Dot features IPX4 water resistance, making it resistant to rain and splashes.
Suitable for RIS rails and G-series pistols
The MRM Red Dot comes with a 22 mm Weaver/Picatinny/RIS mount and a mounting plate for G-series pistols compliant with the Tokyo Marui standard. This makes it easy to mount the sight on various replicas.
The sight also features horizontal and vertical adjustment capabilities with an adjustment increment of 1 MOA per click, a maximum adjustment range of 80 MOA and a parallax of ≤ 3 MOA, set at 50 yards.
