I ordered a lower, upper and mlock handguard on Thanksgiving. Received the upper right away, but never got a receipt and after 8 emails and multiple phone calls that no one ever answered I disputed the charges with my CC. Because I never heard from them, I replaced the lower and the Mlock handguard through other sources. The day after I completed my gun build, I get an email (8 weeks after I ordered it) that the lower had shipped. Still NO handguard and now have a lower I don't need. Aero Precision is pathetic. If you order from them, pray you don't have any issues because you will not be able to resolve them.
