If you find anybody who ships Garand Gears Ported gas plugs to Canada, please let me know.

I'm curious as to why you think you need an adjustable gas screw. I've been shooting/collecting the M1 rifle for just shy of 40 years and have never needed one. Just feed it M1-compatable ammo or reload with M1-specific loads and you'll be good to go.

'pocketfisherman", who is a CGN member, was selling an adjustable plug very similar to the McCann. I don't know if he is still doing this. I picked up 2 of them to use with slower than Garand spec powders in 7.62 Garands and they work well.
