Before, when the old gun laws were in use, a rifle/carbine has to be at least 61 centimeters long stock extended. No requirements existed about the barrel length. With the new (& current) law, there is no longer a requirement of length...pretty antything is allowed.

I love you FN Mauser trainer....none can be found here ! No ABL rifles were sold to the public (except some SAFN brought back from the USAicon...go figure : ABL rifles sold to an US importer, then sold back to a Belgian importer & finally sold to Belgian customers).
