I ordered the Aero Precision enhanced m-lol handguard from Arm or Ally. It came with no barrel nut. Nowhere during the ordering process nor on the website did it ever indicate that it came separate. When I emailed Arm or Ally the only responded that the handguard doesn’t come with one. When I replied stating that their website never indicated that they never returned another message again. The barrel nut cost me an additional $50 plus shipping. I would never recommend this company if this is the way they are used to doing business. Their lack of communication and their lack of purchasing information in addition to their failure to care after they had received the money they were after shows their true heart. DO NOT DO BUSINESS WITH THIS COMPANY
