Ok guys, I've looked around and haven't been able to find a answer. I'm wanting to build a AR-9 but instead of using the standard Glock or Uzi mags, I want to use M&P mags. Does such a lower exist?
I've seen them complete for around $240. Find the exact lower you want and just sign up for email alerts. They almost seem to make them in runs and you won't have to wait long.
I priced out an AR-9 very recently @ about $700 with a 13.5" keymod rail(you could save a little).
I ended up with a Beretta CX-4 Storm because a deal I couldn't pass up... Still on my radar though.
Yea I've looked at the JRC's before but I was really hoping to piece together a AR-9 and not a "AR Like" whole rifle purchase. May end up buying the JRC anyways though.
