Nimrod, the gen II/DPMS pattern idea is a good one. That way you can use P-mags if you want.
Armalite AR10s use PMags too.
Just the older ones from the '90s don't.
You are kind of right, but off a little on the timeline. Mine was made in 2011 and is considered a "B" series. The "A" series was introduced in 2012 and it can use p-mags. That one totally slipped my mind, until you brought it up. Good catch Tyrone. When i think of the Armalite AR10, i always think of the old ones that take the steel mags.
