Welcome to Airsoft Canada, I suggest you take one of the following suggestions.
1. If your over 18, get out to a local game in your area and get age verified then purchase a better quality product either through a retailer here or another of your choice.
2. If your under 18, wait until your old enough then follow the advice in number 1. OR
3. Look for a field in your area that will allow you to play while underaged but keep using your walmart gun until your ready to upgrade to something a little more expensive.
