To benefit, you must be a member of one of the plaintiff classes - members, current and future, of B&T USA, Firearms Regulatory Accountability Coalition, Gun Owners Foundation, Gun Owners of America, customers of Palmetto State Armory, Silencerco Weapons Research, Silencer Shop Foundation, and residents of the States of Alaska, Georgia, Idaho, Indiana, Kansas, Louisiana, Montana, North Dakota, Oklahoma, South Carolina, South Dakota, Texas, Utah, West Virginia, and Wyoming.
Beyond that, many states still require registration under the NFA for you to possess suppressors, SBRs and SBSs so you need to know your state laws to know if you can benefit from this ruling.
Also, keep in mind that the government can still appeal the ruling so it's not over just yet, even for those covered by the current ruling.
