Aero Precision

Founded in the early 1990’s as a simple job shop in a garage, Aeroprecision got its start supporting Boeing’s offload work.
Aeroprecision quickly gained a reputation as the “go-to” shop for contracts and projects from other vendors that were either late or considered too difficult for them to manufacture. But, thanks to the talented team at Aeroprecision, these challenging projects became our forte.
Today that tenacity and passion for perfection drive us to continue building the best products on the market. Our dedication to our products, however, translated well in our commitment to our customers. We know that building a great product is only half of the relationship. We’re committed to providing our customers with the best product at the best price right when they need it. It’s this kind of integrity that translates to great value to our customers and sets Aeroprecision apart from the rest of the field.

Just start with sand paper on a flat surface and remove material lightly on both sides until it fits. I would rather just get it to fit the. Send it back. It's not that big of a deal in my opinion.
If you decide to keep it and file/sand down the sides of the lug to make it fit, do not be concerned in the least bit of excessive wear between the lug faces and the sides of the lower leading to some imaginary excessive slop. We're not talking about some high speed sliding surfaces. There is no loading between these surfaces. You're just opening and closing the upper for cleaning, lube, maintenance, etc. There's more wear between the pushing and pulling of the takedown pin and the lug hole and that's pretty miniscule to begin with. Whenever you lube your pivot and take down pins, that lube will migrate all over the place, including the sides of the lug. Unless you are obsessive/compulsive about the very little "wiggle" between upper and lower, I would not give it a second thought.

My friend almost sprung for one of those Delaware lowers for a build but I told him to wait for an Aero instead after my good experience. I'm glad he listened.
