Hats off to Tiffany at
www.canadianairgunsupply.com reception desk! She knew little to nothing about specific products but gave me loads of information! Capitalairsoft.com uses them and so I emailed him about the G36 gotta call another store this afternoon and then I'll post again.
By the way the websight is under construction she said, so as far as what is what I guess we'll have to wait and see!
