I have a like new Bushmaster M4A3 with a 14.5" barrel with a fixed Phantom flash hider. It has an ARMS rail system which has a removable top rail for optics to allow co-witnessing, ARMS rear flip up sight, GG&G front flip up sight, four rail gas block, vertical fore grip, Magpul CTR stock, Magpul MIAD full grip kit. Has approximately 500 rounds through it, probably less....I am the original owner and just haven't shot it much. Will sell for $1200 shipped or FTF within very reasonable distance of Chattanooga TN. I have over $1700 in this setup. USPS Money Order. IM or email with questions. I will consider parting out the rifle to good offers.
