Quarter Circle 10 MP5 AR PCC | SHOT 2017

    Quarter Circle 10, the Pistol Caliber AR company has made a name for themselves with their Glock mag fed ARs. Now they have made a lower that can use MP5 magazines. With ETS making MP5 magazines, I think these will be a hit.

    They also have a different side charger on the upper receiver.
