Ooops, there goes that opinion again
<Edit: Someone will I am sure bring up a James Yeager video... well if you have ever spoken to James or taken a class at Tactical Response, ..... you would know how much faith to put into that guy.>
I have taken a few of his classes and have the opposite opinion of him.
I have the sights on my AK, AR, and pistols. They work well for me.
Didn't mean to start a debate but thanks for the info guys .
I should've mentioned that these would be for 60 year old eyes and no competitions .
