Aero M5 "Freedom" receiver set, 18" Faxon heavy fluted match series barrel, 15" Mlok free float handguard, .308 BCG mil-spec black nitride, 0.75" adjustable gas block, Rise Armament RA-140 3.5 lb single stage trigger, Magpul grip, rifle buffer tube. This was built by a gunsmith who lapped the upper receiver and "bedded" the barrel with green loctite. This should shoot under 1 MOA with proper barrel break in and decent ammunition, but I have yet to put any rounds through it. All parts are brand new minus the trigger which I had laying around but it is pretty much like new as well. I could swap the rifle buffer system out for a carbine buffer system if so desired. I will include a soft carry bag also. $1000 OBO. Feel free to message with questions.
