I ordered 2 uppers on 15 July 2020. Still waiting 20 weeks later. Website says orders ship within 18 days but not in my case. No response to many emails. No response to the 2 complaints filed with BBB. Phone number given on the invoice goes to a Gold Mining company. I think I may have been cheated out of the nearly $800 that I paid them. User's recommendation: Never ever order from ar15tac. Beware. Fraud.
