Thorsbear,
Thanks for the information on the set screw on the metal cocking tube. I’ll see if i can come up with something to go over the barrel and into the tube. Based on the export schedule I won’t be receiving the tube until February so I’ll update then if I have any issues with CBSA. It’s the same company out of Arizona that’s supplying the cocking tube and doing the export and import so i’m hoping it will arrive here without any issues. But at least i know not to be surprised if it doesn’t make it.
On the other hand i ordered some mp5 airsoft parts including push pins and a collapsible stock for my full length gsg that were all clearly labeled as mp5. That package spent i think 30 days with CBSA, was opened and inspected and resealed with yellow CBSA tape and nothing was seized and duties and taxes weren’t assessed. I received that package last month in November.
