massachusetts gun laws

Maybe a good place to start:

MA looks a lot like CA with regards to gun laws, mostly stupid and useless designed simply to discourage firearm ownership. If you have an AR-15 or AK-47 type firearm with a 20 or 30 round clip, you might have to make them "compliant." This can range from simple, toss all your 20 and 30 round magazines and replace them with 10 round magazines to complex like buying new lower receivers, and installing a "bullet button."

Not trying to encourage you to break or bend the laws. But you may want to simply store any non compliant guns with a relative in PA until you are completely familiar with MA laws.

Hope this helps.
