AR038801 Rock River Arms Mid-Length A4 14"/16" Upper Half 5.56/.223

This is the shortest upper you can get from RRA. These uppers are custom made for us by Rock River Arms master gunsmiths. The barrel is 14" in length with a perminently affixed extended A2 flash hider for a legal total length of 16"s. Why buy a SBR (Short Barreled Rifle) and have to wait for government approval when you can get a short 14" model now!
