Browning Zerust

[NSP]

I picked up some of those little Zerust thingies at that ammo sale and the stats on the back say it's good for 1 year. My question is how do you activate it? Does anybody know? I've looked around and haven't found anything. If I turn up deuces here then I'll just call browning myself.

Nobody knows huh?
