Guys, I post this as a caution, just to inform, not criticize! If you are happy with your purchase more power to you. I’d just hate to see/hear anyone getting in trouble over our @!#$ed up state gun restrictions. I noticed a lot of people excited about being able to pick up so called "Refurbished" Pre Ban AR mags at the recent Mass gun show. Unlike selling Mass banned guns, mags are not controlled and monitored by the state and local dealers in the same way as guns. The burden is on you to know what you're buying, if you're caught with mags in violation of Mass restrictions you'll pay the price! In recent years I've seen people selling new Glock, AR, and other mags at the shows. Mass residents are thrilled to be able to finally get their hands on hi capacity magazines at reasonable prices, not knowing (or caring) that these are new production, NOT Mass legal. There are no stamped markings on these mags since it’s not required in most states now but there are differences so LEOs can distinguish these from Pre Ban mags. Just because someone is selling mags at a gun show doesn’t mean they are legal in our state, EVEN if they tell you they’re okay. Just ask yourself, why are no in state dealers selling these mags? If a Mass dealer and saw someone selling like new AR mags (with Magpuls no less) for $20 don’t you think they would buy the guy’s entire stock up on sight? Hey, if I’m wrong, then you are lucky to have found a bargain in this twisted state of ours, but if you’re wrong you might not be so lucky.
