Unlike the majority of open sights for handguns 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 with a single piece of aluminum that can withstand thousands of rounds without any problem.  The unique battery chamber design, 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 are 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 select handgun models, such as Glock, by taking off the picatinny rail mount and mounting it on the adapter plate (sold separately).  To remove the picatinny rail mount, loosen the two top screws on the main chassis.

Midas BTR OS11 Model has an OS 11 reticle in it. Please click the link for detailed reticle subtensions.

    I bought a OS11 for my Walther Q5 Match, right after buying the gun. I choose the Athlon based on previous experience with their rifle scope that I have on my 300 Win Mag. The other thing I liked about the OS11 was the battery tray vs other brands. My first experience was less than I expected. The unit failed the first time out and needless to say I was quite disappointed. I called Athlon and got a return autho and a shipping label, and about 10 days later I received a new unit that now has 500 rounds through it flawlessly. while the optic did have an issue, Athlon made it good right away. Very happy with the performance of the new OS11, and how quick and easy Athlon solved my issue.
    Things break, customer service makes happy customers.
    Thank you Athlon
