If you can't hit an "ON" button how are you going to manage a safety switch?
They don't have an "on" button.
Aimpoints have a rheostat that increases the brightness of the dot. If you have it too high, it will blind you at night.
Which hand are you going to use to do this with? Your firing hand or your off hand?
How are you going to activate your light? You are using a light right to identify your target before you shoot aren't you? So if you are doing it with your firing hand, how are you going to make the shot?
Will I even need to acquire a perfect sight picture or be able to do anything but point and shoot with a rifle at the sightline distances (<10')
available in my bedroom?
I know what you are trying to do here, but what you actually did was present the specific case for RDS/Holographic sights. You don't have to have a "perfect sight picture" or even have your face on the stock to use them. If the dot is on the target, that is where the bullet will go.
Well, technically, it will be about 2.5 inches low at 10 feet, but close enough for a COM shot. If you are triying for precision crainial shot, you need to hold on the hairline.
Anything you have to do other than pick the gun up and shoot, will slow you down.
If you can make a shot COM on an agressive target in the dark without using any type of sight at all. You should open up a shooting school and make enough money to retire teaching all the SWAT and Military your CQB tactics....
Am I correct that you neither own an optic nor have you actually tried doing any of this before to actually develop your own TTPS?
