Firearms bolt carrier assembly |
摘要 |
A bolt carrier assembly has a housing (300) for supporting a bolt (317) and a P cross-sectionally shaped member (301) having the longer side of the P-shape secured to the housing, the P-shaped member being forwardly extended with respect to the bolt. The main drive spring (307) is located alongside the wrapped-over portion of the P-shaped member which main drive spring is arranged to provide motion to the housing and P-shaped member. An anti-bounce weight (354) is mounted inside the wrapped-over part of the P-shaped member and has a spring at one end which is compresed by the anti-bounce weight when the P-shaped member is suddenly retarded by the housing to which it is attached striking the barrel assembly. A latch (326-329) is spring biassed and shaped and dimensioned to interleave locking lugs (322) on the bolt (317), the latch being longitudinally retractable with respect to the housing.
