That is not an AR BCG - there is no room at the back of the receiver for the travel of an AR15 BCG.
Nobody really knows what the RCMP criteria is.
One thing I’ve noticed with the recently approved Turkish rifles, and the Henry Homsteader, is that the top of the barrel is exposed in a more traditional hunting rifle fashion. Then again they banned the FNAR and that was of similar construction.
They do like to keep us guessing, and going out to replace banned rifles with soon to be banned rifles.
Personally I just buy what I want.
