Yeah our Airsoft laws are a bit more screwed up then UK laws I think.
UK is a bit easier, but still.
Basically we have an Age Verification system in place here.
You meet up with a representative, show him your ID proving you are 18+
He puts it in the system, then a mod will update you as Age Verified
(As you can see, most of us here have "Age verified" under our pictures or user names)
Once you are Age Verified, you can access the guns for sale on this website.
Full black, metal/plastic whatever, there is no legal restrictions in the Classifieds on this website.
Just do not buy outside of Canada and you're good to go
Best of luck
