How strong is the front sight post on a Colt? I have an F post on a Colt 6721. I am wondering how much force/abuse that it can take before damaging it or knocking it off center and if there's a way to accurately determine if it is off center.
Had to replace a stubborn flash hider and didn't have a vice block and used the front sight post as leverage.
Also, while I'm here. Which way should a crush washer face when you install it? I seem to have run into some conflicting opinions on the matter and can't decide how I should install it.
Bonus question: Would replacing things like crush washers on a Colt AR lower it's value in your opinion?
