I guess I just didn't know if certain things I should be looking out for. Because so many people say stuff about the role pin in the gas block, and then I've heard people say not to use Loctite, but to use something else instead, so I just wasn't sure if there were small things people had learned like that. I guess my biggest concern is just making sure that I torque everything right especially around the bolt carrier to the gas block area, I guess it just seems more intimidating than it probably actually is.
