Thread: Complete AR-15 Lower Receivers Mega/Rock River Arms

I currently have several complete lower receivers in stock, and a couple stripped receivers. All receivers are made by Mega Machine Shop and are built with Rock River Arms Lower Receiver Parts Kits and Rock River Arms stocks. The choice of stocks are as follows:

A2 Complete Mega Receiver $250


M4 Complete Mega Receiver $275


Operator Complete Mega Reciever $350


As stated above all complete receivers come with everything needed to complete your lower, including buffer and spring. All that is needed on your part is an upper receiver to pin on it.
