This is a Aero M5 308 with a 22" build upper from Aero Precision.  All gun parts are purchased directly from aero precision.  I currently have a BCA 3-9 sight, magpul ms2 sling, olight odin light, and two magazines for it.  I have put approximately 100 rounds through it.  I like the gun, just listing it for financial reasons.  If you are local to Hillsborough area and are interested, you can come to my house and test functionality.
