pm和隐藏式pm7.62mm狙击步枪
中文名称: 英国pm和隐藏式pm7.62mm狙击步枪
研制国别: 英国
研制机构: 精密仪器制造公司
分类: e922.12

简介
pm7.62mm狙击步枪是英国精密仪器制造公司为执行狙击任务而研制的步枪，其设计思想是：不管枪管清洁是与否，都要做到首发命中。
pm 7．62mm狙击步枪系统主要有步兵用、警用和隐藏式3种。步兵用pm狙击步枪已装备英国陆军，被命名为l96a1式，非洲、中东和远东一些国家的陆军也装备有此枪。
警用pm狙击步枪采用单发射击方式，可发射多种口径马格努姆枪弹。1000m距离内使用0．300in温彻斯特马格努姆和7mm雷明顿马格努姆枪弹，1000m以外距离使用8．6mm枪弹。
带消声装置的pm狙击步枪也在生产，这种枪发射特种亚音速弹，在300m射程内弹道较低伸、风偏不大的情况下，命中率较高。
隐藏式pm 7.62mm狙击步枪是pm狙击步枪系统的最新型，也是带消声装置的pm狙击步枪的可拆卸型，已投入批量生产。
