Determination of the Tier5® MBC®
As a result of the recent unofficial opinion of the New York State Police regarding the Tier5® MBC®, we contacted the International Firearms Specialist Academy (IFSA) and asked them for a legal determination of an AR15-type firearm fitted with the Tier5® MBC®. The IFSA made the determination that an AR15-type firearm fitted with a Tier5® MBC® changes the method of mechanical operation of a self-loading firearm, to a manually-loaded firearm. In short, an AR15-type firearm fitted with a Tier5® MBC® is no longer a semiautomatic firearm. The IFSA Determination Letter is available below or in the provided link. IFSA Determination Letter
