This brand new addition to the AR-15 family will allow withering firepower in more affordable 9mm ammo.
The guys at GY6vids give a complete review of the Freedom Ordnance FM-9 belt-fed AR-15 upper receiver attachment.
It is first of its kind to hit the gun market that allows you to mount the upper receiver and barrel group onto an AR-15 lower receiver, providing a groundbreaking 9mm belt fed system. It comes in one convenient kit and even provides two different barrel lengths: one in 11 inch and the other in 16 and half inches.
With a 150-round belt bag, this looks like a blast to shoot at the range, and an innovative concept for the AR-15 platform.
That's a neat gun, it reminds me of a little brother to the military's 5.56mm Squad Automatic Weapon, or S.A.W. as it is commonly known, but in more affordable 9mm. It will be interesting to see how this system is received in the near future, so keep an eye on Freedom Ordnance.
