I personally like red dot optics for their fast target acquisition, but they require maintenance. Specifically, having a schedule for changing the batteries is a good idea. However, there’s still the possibility you may forget, or even get a bad battery that dies faster than it should. For this reason, an optic that doesn’t require batteries, like the Meprolight Mepro M21, allows you to set it and forget it.
The Meprolight Mepro M21
Featuring a durable aluminum body construction, the M21 can handle rugged use in harsh environments. Likewise, designed to withstand water submersion and drop testing to MIL-SPEC certification requirements means your optic can handle hard use. In fact, the M21 was developed for the Israel Defense Force (IDF) and remains on active duty today. So, it has been combat-tested and proven to hold up under adverse conditions.
The dual illuminated 1X reflex sight provides instant, all-light aiming without batteries. The M21 pulls available ambient light for a bright reticle by utilizing fiber-optic illumination during the day. Correspondingly, the sight uses tritium at night to ensure a bright reticle in low and no-light scenarios. Additionally, according to the company, the transition between the two systems is instantaneous and automatic.
The M21 features a large 30mm window for greater FOV, allowing you to shoot with both eyes open. Housed within the window are five amber-colored reticle options. You can select between Bullseye, 4.3 MOA dot, X, 5.5 MOA circle with a dot, and the Triangle. According to the company, the 5.5 MOA circle/dot and Triangle are the most popular.
The Mepro M21 is suitable for Night Vision Goggles or scopes, including those with Gen III tubes. Likewise, placing a magnifier close to the optic shows no decrease in the field of view. Because of the battery-less operation, there are no buttons, on/off switches, or maintenance.
Although the self-illuminated feature is great for always-on operation, it comes at a cost. Since the optic uses tritium as its light source at night, it will eventually lose its illumination. However, according to the company, the tritium illumination is guaranteed for ten years.
So, it might be a non-issue, because who knows what kind of technology will be available in ten years, and you might be ready to switch anyway. But it is still worth being aware that the sight has a shelf-life of only ten years.
The Meprolight Mepro M21 is available now with an MSRP of $479.99. For more info, please visit Meprolight.com.
