On top of that mags are not serialized. I remember there was talk of people "registering" hundreds of mags even though they only had a few thus leaving them room if they felt like buying more. They could just say they had them all along, and nobody could prove otherwise unless they did something dumb.
Yes, I was suggesting that if people understood the risks fully, they do exactly that.
Here are the scenarios.
1) you don't buy the additional mags and your declaration exceeds what you actually have. So what. You sold them, destroyed them, stored them out of state.
2) You buy additional (careful they aren't date stamped. note - some new AR15 mags are date stamped on the INSIDE) mags after the fact in a non stupid way. (with a CC over the internet would be stupid. With cash at a gun show in RI would not). Nobody knows any better.
One final thing. As recently as 5 years ago, most of the gun websites I frequent had a policy that you couldn't give advice to help others circumvent the law. Although I didn't agree with it, I of course complied because whoever provides the forum sets the rules.
In the aftermath of Sandy Hook, I began having discussions with others about the advisability of providing advice on how people could avoid unethical and in some cases unconstitutional laws. There is nothing illegal about doing this. If I do provide this info, I stress what aspects are legal and what aren't.
I'm old enough and have enough means to pretty much buy my way around almost any gun control law I encounter in CT or MA. There are always LEGAL ways around these laws. You just need to throw money at the problem. For me, as someone in the middle of his life, with young children, civil disobedience is not worth the risk. So I make sure I am 100% legal. Always.
But for others, it might be a reasonable risk. For those people, they should know the risks. Ask lots of questions. If someone references a law, ask for a citation. Don't be stupid. Its all about realistically assessing your risk tolerance and behaving accordingly. My risk tolerance, with young children is ZERO. But who knows. When they are grown and out of the house, that may change.

p.s. My attitude re the CT AWB was exactly the opposite of what many gun rights people advocated. I wanted to drown them in their own 5h1t. The way the law reads, a pistol grip or a magazine release could be interpreted to be an assault weapon. I sent in close to 100 AW registrations for every pistol grip, mag release, gas tube, bolt carrier group and telescoping stock I owned in addition to registrations for every handgun I owned because some day I might want to put a threaded barrel on it and since they were all purchased legally, the state already had DPS-3 information on the firearm.
One of the beautiful things about registering pistol grips is that they didn't have serial numbers. In some cases that required a couple of back and forth by mail to sort out. Wasting more of their time.
