this is going to sound illegal but i assure you its not. I have a BRS-99 and have designed a lower for it that accepts trommel magazines which are exempt fromt he mag capacity laws beacuse they were designed before 1910. it is legal because on this particular gun the upper is the serialized controlled part. when the lower is complete it will be the first legal high capacity centerfire rifle in canada since the 70's (that im aware of anyways). cant wait to show everyone and hopefully sell them on the EE!
