Don’t forget if you bought your Airsoft gun here at JF you receive FREE LABOR on that gun for the first year, and 1/2 price labor FOR AS LONG AS YOU OWN IT. JF offers a full service shop doing repairs and upgrades on all airsoft guns. Even if you didn't buy your gun at JF we will work on it. Remember if your gun is making a strange noise, or just doesn't seem to be working correctly, DO NOT keep shooting it to see if it gets better, you will most likely only do more damage. If you like to work on your own gun or are just curious about how it works we are providing links to videos to help you troubleshoot, and maintain your guns.
