Holosun 515GM

The Holosun 515G-M is a rifle red dot sight designed in the style of the Aimpoint Micro Series, and suspiciously similar to the Sig Romeo4T PRO. The M in its denomination indicates made of 7075 aluminium. The IPX rating of this device is 68, above the usual 67 of Holosun products. The fact this sight comes without a solar panel is one of the strengths of this device in our opinion.

The reticle modes available are 2 MOA dot and 2 MOA dot surrounded by a 65 MOA ring resembling Eotech’s.

The “shake awake” feature means the device will power off automatically after a few minutes of not detecting movement, and will power on immediately after detecting the slightest movement or vibration. However, we recommend turning off the device when not in use.

It comes with all the hardware necessary for its installation and a quality detachable Picatinny mount with a QD lever. The mount height is Holosun’s/Sig Romeo’s interpretation of lower 1/3rd cowitness (1.63 inches), as opposed to the traditional interpretation of 1.54 inches. We recommend applying Loctite 243 on the screws and marking the screw heads to identify if they become untorqued.

The footprint of this device is Aimpoint Micro, so it’s easy to find alternative mount types and heights. As a general rule, high-rail weapons such as the AK, G36 and MP5 platforms should use lower mounts.

Flip-up lens covers are included, as well as an ARD (anti reflection device) or “kill flash”.
