Athlon Optics MIDAS BTR RED DOT OS11 - 1X Open Sight (ARDOS1 Reticle) 403001

Athlon Optics

$229.99
  • Reticle etched on glass that provides excellent backing support for complex reticle design and offers great durability and much higher shock resistance to recoil
  • Fully multicoated optics effectively reduces reflected light and increases the transmission of light giving you a Brighter image than Normal single coated lenses
  • Multiple adjustable Illumination settings provide best visibility under different ambient light environment
  • Heat treated one piece chassis gives the scope extra strength. A one piece chassis also is better at keeping moisture out thus keeping your scope fog proof for the life of the product
  • Nitrogen purging dramatically reduces the moisture inside the tube and helps maintaining Fogproof and waterproof


Rather than like the majority of open sights in the market that have two separate upper pieces of chassis that hold the lens in place with the tendency of the lens cracking, the OS11 upper body is constructed by a whole piece of aluminum that can withstand thousands of rounds without any problem. The unique design of battery chamber, located at right side, allows you to change your battery effortlessly and quickly without dismounting your sight and losing your zero. The illumination switch buttons is conveniently located on left side and can be simply turned on and off by holding on the + button. Furthermore, you can mount the sight on certain selective handgun models, such as Glock, by taking off the Picatinny rail mount and mounting it on the adapter plate ( you need to buy the adapter plate separately) that has been mounted on your handgun already. To remove the Picatinny rail mount, just simply loosen the two top screws on the main chassis.
