ORDERS

All of our inventory is LIVE DATA. If a part shows in stock, we have it in stock. We do not believe in "Back Ordering" 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 if you have any questions or if you are unsure of fitment.
