为适应国际市场需要,我们以美国COLT WOODSMAN5.6mm运动手枪为基型,开发了223型5.6mm运动手枪。 原枪轻便小巧,结构紧凑,只有套筒、套筒座、弹匣三大组件。其自动原理为自由枪机式,惯性闭锁机构,内藏式回转击锤单发发射机构。开发工作是按用户要求,在原枪外形不变,原结构不大动的前提下进行的。通过分析,在测绘的基础上,开发枪增设了5个机构,即空仓挂机、弹匣保险、击锤待发指示器、可左右手操作的扳把、击针保险。这5个机构都安装在厚度只有16.1mm的套筒座上,难度较大。下面将其结构特点作一介绍。
In order to meet the needs of the international market, we have the United States COLT WOODSMAN5.6mm sports pistol as the base, developed a 223 5.6mm pistol. The original gun light compact, compact structure, only the sleeve, sleeve seat, magazine three components. The automatic principle of the free bolt-type, inertia latch mechanism, built-in rotary hammer single launch mechanism. Development work is based on user requirements, the original shape of the original gun, the original structure is not a big move under the premise. Through analysis, on the basis of surveying and mapping, the development of guns added five agencies, namely, short positions hang up, magazine insurance, hammer to be the indicator, can be manipulated left and right handle pull, needle insurance. These five institutions are installed in the thickness of only 16.1mm sleeve seat, more difficult. The following describes the structural features of an introduction.
