Need help with my Troy DOA fixed rear sight. If using a standard military 300 meter zeroing target do you use the larger or smaller DOA sight?
Second on the larger DOA sight is it normal for the rear sight to be blurred out and the four white lines not be visable?
Just wondering if its just my old eyes or this is normal for these sights Thanks in advance!!

I have a regular fixed Troy sight and several of their folding sights, but I would say it is normal that the rear sight be blurred out as you usually focus on the front sight. I don't know about the DOA sight but I thought the regular Troy sights have the same plane aperture. The larger aperture should provide quicker acquisition of targets in more of a low light, close up engagement of targets type of situation.

Thank you sir

The larger aperture is for quick acquisition and close in work. For longer ranges and more precision work, you want the smaller one.

In either case, the rear sight blurring is normal. The only thing that should be clear is the front post when aiming.
