Personally if the RCMP can't convert it and can't find out how to convert it from FN. What chance does Joe Blow have?
The FRT lab should not require any input from the manufacturer. They need to ask themselves these questions and not the manufacturer.
Can I easily convert it to full auto with readably available parts? No.
Is it based on a prohibited? No.
Does it meet OAL requirements? Yes
Does it meet barrel length requirements? No
result
RESTRICTED
How hard is that.
