M4e1 not compatible - Aero Precision AR15 Gen 2 Enhanced M-LOK Handguard

Aero really needs to make it a point to say that this is only compatible with the m4E1 ENHANCED upper. They even should bold it and upper case it. I don't even see it listed in the description here at ALL. The point of me buying this handguard was so I didn't have to buy an extra barrel nut, but then when I get the handguard I found out you need an extra enhanced version. The company can't be clear in their description and advertising. There's a reviewer trying to put that all on me as the buyer for not doing enough research. That's a bunch of BS.. when you read a description for a product that piece of information is important to be listed in there, I'm curious to where the other reviewer got his proprietary information. He probably learned by ordering the wrong parts like I did lol.
