All of our inventory is LIVE DATA. If a part shows in stock, we have it in stock. We do not "Back Order" parts. Barreled Upper Orders can not be changed or modified in any way after they have been placed. Please contact us BEFORE you place an order with any questions.
Due to increased fraudulent activity, customers with different billing and shipping addresses or credit card names will be required to submit a copy of their driver's license to confirm their identity. Once confirmed, customers will not have to resubmit on future orders.
