I know this is an old thread, im sort of skimmed through it for the answer to my question.
Why do i have to seal the whole mag closed? If i epoxy a rod under the follower, the mag at that point is a 10 round permanent magazine. Now the argument is that i can dismantle the magazine and add in a new follower without the rod. At this point, the magazine has been dismantled and is now a rebuild kit which is legal to own. Putting in a new follower and assembling a 30 round magazine from that point would be a crime. But prior to it being dismantled, it was legal. Does anyone get what I'm trying to say?
