However, if they are not, please feel free to contact- us. We will do our very best to assist you and solve any existing issues! Q: Does my Lancer Tactical airsoft rifle have a warr-anty? If so, how do I utilize that? A: ALL of our AEG's sold through approved retail channels (new, and not used or second-hand) come with a 1-year warr-anty that BEGINS the day you purchase the item. To take advantage of your warr-anty, please register your products on our "WARR-ANTY REGISTRATION PAGE" under the support tab. You will need your proof of purchase, your serial number, and your model number (found on the box). Q: What will void my warr-anty? A: Removing your orange tip or opening up your gearbox will be immediate cause for voiding your war-ranty. Do not worry though, if you still need our assistance we will be more than glad to help. We can do authorized repair work on your Lancer Tactical products for a fee and get it back up and running if your warr-anty has been in fact void.
