About Athlon Optics Midas BTR OS11

How can you enhance your shooting accuracy and speed The Midas BTR OS11 Open Red Dot Sight with 3 MOA Dot Reticle is the answer for shooters seeking a durable, high-quality, and reliable aiming solution. Unlike many open sights that utilize a two-piece chassis prone to lens cracking, the OS11 features a robust, heat-treated one-piece aluminum chassis. This design not only provides exceptional strength and superior mechanical integrity but also ensures the sight can withstand thousands of rounds, maintaining its integrity and performance.

The innovative battery chamber, conveniently located on the right side, allows for effortless and quick battery changes without the need to dismount the sight or lose zero. This feature saves valuable time and keeps you focused on the target. On the left side, the illumination switch buttons are easily accessible, enabling shooters to turn the sight on or off with a simple hold of the '+' button, streamlining the operation process.

For those using selective handgun models, such as Glock, the sight can be directly mounted by removing the included Picatinny rail mount and attaching it to an adapter plate (sold separately), which is pre-mounted on your handgun. This versatility makes the OS11 a top choice for various shooting platforms.

The sight boasts an etched glass reticle, providing excellent support for the complex design and offering greater durability with higher shock resistance to recoil. The fully multi-coated optics reduce reflected light and enhance light transmission, delivering a brighter image than standard single-coated lenses.

Constructed from aircraft-grade aluminum, the Midas BTR OS11 is designed to protect world-class optics, no matter the conditions. The one-piece chassis construction not only adds strength but also effectively keeps moisture out, ensuring the sight remains fog-proof throughout its lifetime.

The sight is waterproof, allowing for use in the harshest weather conditions or even if accidentally submerged underwater. It is also fog-proof, enabling immediate target engagement when transitioning from warm interiors to cold ambient temperatures. The robust mechanical system is designed to withstand 600G of recoil for 1000 times, making it shockproof and suitable for the most intense shooting scenarios.

Nitrogen purging significantly reduces internal moisture, further maintaining the fog-proof and waterproof integrity of the sight. The included Picatinny rail mount is compatible with most bases used by hunting and tactical rifles, adding to the sight's adaptability.

Choose the Midas BTR OS11 Open Red Dot Sight for a sleek, modern, and versatile aiming solution that offers a wider field of view, easy target acquisition, and a clear aiming point for accurate shooting at short to medium ranges.
