Andy, who blogs at GunPath.com, sent us a photo of his AR-10 style rifle chambered in .308 Win. It was build with an Aero Precision M5 .308 stripped lower with factory FDE Cerakote, Aero Precision assembled upper receiver with Aero Precision 16″ .308 stainless steel barrel with a mid-length gas system and Lancer Nitrous compensator. The stock is a Magpul CTR in flat dark earth color and the handguard is a Fortis SWITCH 15″ rail system. It is topped off with a Vortex Crossfire II 30mm 1-4×24.
