Well, glad to see my thread came back to life!
AR-15s and AR-10s will function just fine with the bolt rings lined up. It's only a myth that they won't.
Quite right, that is a big myth. When the bolt is inserted into the bolt carrier, part of the resistance you feel is bolt carrier compressing the gas rings. When the gas rings are compressed the gaps close off. It doesn't matter where they line up.
Fully automatic weapons most certainly do have a place on the modern battlefield. It doesn't take any real skill to put a bullet into someone from across the room with a rifle. With the exception of one or two target areas, you are not going to see instant incapacitation from any rounds you fired. This all boils down to doing damage. You need to do as much damage to the threat in the shortest amount of time to cause him to either volutarily or involuntarily quit the fight. This means multiple rounds in a very short time frame. This is best accomplished with fully automatic fire.
Badgersmilk has his life experiences on which he bases his decisions, as do you and I. Being first through the door more times that I can count, nothing has given me comfort more than knowing I have one more selector position, should I need it. That's my life experience.
I would also go easy on the attachments tirade. Most attachments enhance the operators ability to work in different environments. Sure, there is a lot of worthless crap out there, but there is some good stuff. Having the wisdom to know the difference is the big issue.
Let's try to keep this thread on track. If you want to discuss which rifle is best for a SHTF scenario, then please start another thread. This is about battle rifles, which are generally considered to be 308, 30-06, 8mm, etc.
Gentlemen....carry on.
