I gotta agree with bother Rene on this. I don't see a standard coming as long as there are hard-asses (like me) with the Armalite 10B platform. They did (Armalite) invent the damn platform (Stoner/Fairchild/Armalite that is). But the rest of the industry has adopted the SR25/DPMS patterned rifles. Unless the military outright adopts the platform "officially", there's always going to be the multiple "flavors" of the platform.
Until then. I'll be happy with the equipment I have (knowing that deep down I make all of you guys jealous). <laughs> And just stockpile replacement parts for them.
