All of my rifles have scopws on them, except my Ml. I have two that I was wondering if I should leave the irons on or take them off, I havent used the factory sights in years, Just a scope. One is a BAr Carbine and the other is one of the New Remington 750 woodmaster. Will taking them off affect accuracy ? As I think the barrel might vibrate differently. What do you think ?

Theoretically, you’re probably correct. But practically speaking I doubt you’re gonna notice a difference. Not to slight your rifles in any way, but those models are not bench rest rifles to start with.
