Will a 9MM upper with BCG work on a 556 lower? Is there a mag adapter for a standard lower?
And now y’all got me coming up with plans to put my slide fire on my 9mm AR-9 SBR. Great way to rip through a ton of my $ in ammo. #ingomademedoit
Anyone know if a 9mm ar will cycle a bump stock?

I had an OOB discharge with mine. Never tried it again.
