Buy yourself a brass catcher, I bought one and a bunch of the mounts so I can use it on all my semi's.
I have the 3 Bucc brass catcher, it works really well but I don't know who carries them in Canada anymore.

Edit- found it http://www.4gt.ca/3bucc/
Good idea.
One of the vendors I really like dealing with has these for a measly 15 bucks:
Velcros around the handguard so it'll fit any AR. I'm wondering if it'll perform adequately and let me keep the extra 70 bucks in my pocket.
