Aero M4E1 16-inch Mid-Length General Purpose Rifle with Sig Tango-MSR

The builder calls it the Garbage Can Sandwich: an Aero M4E1 lower and an Anderson upper with a 16-inch Ballistic Advantage mid-length barrel under a 15-inch Expo Arms rail, mixed with parts from a dozen brands. It's a general-purpose rifle with a Sig Tango-MSR 1-6, an offset Holosun 407C and Leapers offset irons, plus a Holosun IRIS-GR3 laser and an Arisaka Malkoff light. A CMMG A1 fixed stock with a trapdoor cleaning kit, a LaRue MBT-2S and a Breek Warhammer charging handle round it out at 11.5 lb.
