I always heard if you don't have anything nice to say, then don't say anything at all.
BUT, I would recommend a FAL over an AR 15 or any .223. After using them in Iraq....I wouldn't piss on one to put a fire out on it.
.308/12guage/.45 Those are calibers to live....or swear by!
I'm not trying to argue with someone that’s been there because I haven't but I have read many articles from both sides of this argument and I'm not convinced. If it's something you don't mind talking about can you give any specific examples as to why .223/5.56 is ineffective?
