Aim-O M2 Red Dot Sight with Cantilever Mount — Black

The Aim-O M2 is an open red dot sight in M2 style with an integrated cantilever mount for 20 mm Weaver/Picatinny rails, designed for shooters who need fast target acquisition on carbines, semi-automatic rifles and tactical platforms. The aluminium body weighs around 300 g and overall length is 130 mm, keeping the unit compact without giving up structural rigidity.

The reticle switches between red and green with two brightness levels each. Being able to choose the dot colour means always having maximum contrast against the background, whether in full daylight or in low-light conditions where red tends to wash out. This is not a cosmetic feature: against a bright background green resolves faster; against a dark one red stands out more clearly. The two intensity levels per colour let you adjust emission without breaking eye contact with the target.

The cantilever mount positions the optic body further forward than the attachment point, extending the sight radius without affecting how the rifle fits in a case. On AR-pattern platforms this produces a more natural cheek weld height, keeping the eye in line without straining the neck. The trade-off to consider is weight distribution: the system's centre of gravity shifts slightly forward compared to a direct mount, which is noticeable in the overall balance during extended shooting sessions, though it remains well within the norm for a red dot in this category.

Key features

• Red/green reticle with dual brightness: the shooter selects the optimal contrast for ambient light conditions without any additional tools.
• Aluminium body at 300 g: sufficient structural strength for recoil-generating firearms without adding unnecessary weight to the build.
• Integrated cantilever mount on 20 mm Weaver/Picatinny rail: adds positioning flexibility along the handguard without requiring separate mounts.
• Anti-reflection and scratch-resistant lens coatings: reduces stray reflections that could reveal position or distort perception of the dot.
• Powered by 2 LR44 batteries: a widely available format — no proprietary cells to track down.
