Pretty much any search I put in yahoo looking for 308 AR information "suppressed 308", "mid vs rifle gas", "DPMS vs Armalite", "308 buffer weight", "308 barrel length velocity", etc, it always finds posts from this site. From what I've read so far I've found what seams like solid information with very polite and helpful responses, unlike some other forums where you get flamed for being a newbie or because you don't have the latest and greatest high-dollar wiz-bang gadget hanging off your rail. Happy to finally join.
