Lifetime Warranty!!

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.
