Hi everyone. First post here, though I cruise everyday. Thank you to everyone out there posting, the advice and knowledge is great. I'm sorry if this topic has been beaten to death, but when I try to find information on Mass Laws regarding pump shotguns, the conversation always turns to semi-auto shotguns. My question is pretty simple. Is it true a pump shotgun will never be considered an assault weapon by MA law? For instance, if I wanted to buy a stock rem 870, but add features such as a combined pistol grip/telescopic stock (knoxx specop stock), put a 2 round extension tube on it, and an 18"1/2 barrel, would that be totally illegal? I've read that pump shotguns don't need to follow the "2 evil features" rule because it is not a semi-auto shotgun to begin with, therefore it can never be considered an assault rifle. I just wanted to verify with anyone who has knowledge on the subject regarding modifications for a pump shotgun such as the rem 870. Thanks again everyone!
