I have AR flat top upper that has a traditional M16 style front sight that's in the sightline of a red dot scope. it really doesn't bother me much but it bugs my wife and a happy wife is a happy life! So I picked up a flat gas block and want to install that but, the m16 style looks to be held in place by two pins. Do these drive out? Or do I need to drill them out? I tried driving them but didn't wack em to hard on the chance of messing them up.
Thanks upfront!
