Oh great here comes the 18+ argument again. I find it rather funny that most of people who get going on this are barely over 18 themselves. But thats just me.
As for a store bring in the Cansoft gear, I am pretty sure that they will follow the rules in regards to the 18+ with ID. The reason being that if they are caught selling to anyone under the age of 18, they will be investigated and fined as they also sell firearms in that store.
