Abstract: A riot faceshield assembly is provided which can be utilized with a wide range of protective helmet designs and sizes, which provides a positive sealing relationship between the faceshield and the front brim of the helmet, which may be pivoted into and conveniently locked in the protective position, and which includes a positive stop member to prevent the faceshield from pivoting downwardly into contact with a wearer's neck or chest when impacted. The faceshield assembly includes a three point or triangular retention system which assures integrity of the unit in the event of either upwardly or downwardly directed impacts.
