aero metal buis . HK style, pretty sure they don't make them anymore. They are awesome.

larue and magpol rail covers and goon tape are on the rail. Helps keep the rail manageable to hold onto when shooting in the heat.

The gun is very accurate . I've shot 1 inch groups with it at 100 yards and sub 1 inch groups at 50 yard using the irons. I have shot otms, frangible, and all sorts of ball ammo through this upper. Never had a issue feeding anything . I have about 1500ish rounds through this upper receiver. Only reason I'm selling it is for funds for something else. Will sell a Sba3 brace for an additional $50. It's brand new. 

This is a older aero upper. Back when they where the industry standard. Before the company went through the company shenanigans.
