The first step to correcting ignorance is to realize that you don't know, which have done. Many people come here with a problem that has been discussed and solved many times. They swear that their local gunsmith or friend that builds ARs knows what he is talking about even though they can't fix the problem. They refuse to learn. Thank you for taking the opportunity to correct your ignorance the easy way.
Stick around and join the conversation. Most of us don't bite, unless you're into that sort of thing. 😄
