Can you buy a semi in 556 in Canada?

Probably not

Browning bar if you can find one. No 223 , but you can b a Sks wit a bayonet

Got one in 30-06

Only restriction on center fire is mag capacity pinned at 5 rounds.(and barrel length)
Dont know of any semis in that calibre.

Can’t think of any off hand. The expensive HKs made the new list. Only reason the SKS isn’t on it yet is the aboriginals made a big stink about it. We shall see what happens in the new year, looks like an election will be forced.

I was looking at the list
now I am not sure if it is the compete list or the new 3 hundred and some they added this year

what I am not seeing on the list is the Ruger Mini-14 now this doesn't exactly fit your 5.56 request , however it does

Ruger came out a long time ago and said Mini-14 marked 223 have a plenty generous enough chamber to take 5.56

they made a Ruger Mini in 5.56 they called it the AC-556 and it was a select fire model for prisons , police , and department of energy the also made the Mini-GB government barrel , these were marked 5.56

the secret I guess you could say is , they used the same reamer on all of them and called government guns 5.56 and civilian guns 223

And 22 semis being banned. No gsg 22 s any more. Browning bar is only semi allowed in 556 or 223

you have a cake and they want a slice , until they are having the crumbs making smaller and smaller crumbs

their goal is make sure you haven't got enough a slice of cake left before you realize it is the last slice.
