Aero upper - Aero Precision M4E1-T 12.5in 5.56 NATO Complete Upper Receiver with Flash Hider w/ S-One Handguard

I bought this upper and it ended up later getting the lower to match. I took advantage of the black friday deals and it came pretty quick. Ive put a couple hundred rounds through it with zero issues. It shot steel and brass ammo eith no problems. The handguard is very slim and light weight for carrying or all day training with. Aero makes great products so you cant go wrong getting one.
