目前市场上的AR系步枪均采用模块化设计,上下机匣都为标准件,可互换通用。常见的AR系步枪通常以更换上机匣组件(包括上机匣,枪管、抢机等)来实现不同的战术用途,具有特色设计的下机匣组件比较少见。图中这款AXTS公司通用下机匣组件采用半自动发射结构,仅能单发发射,弹匣插槽的前方设有辅助握持的防滑纹,握把采用麦格普公司的聚合物握把。保险、空仓挂机解脱杆、弹匣卡笋均为左右两侧设置——诸多操作部件采用双侧设计,这在AR系步枪市场上也难得一见,无疑极大提高了抢械的人机工效,使用非常方便。
The current AR AR rifles on the market are modular design, the upper and lower casing are standard parts, interchangeable GM. Common AR Rifles usually use different casing components (including upper case, barrel, grab machine, etc.) for different tactical purposes. The lower case components with unique design are rare. AXTS company in the picture below the general use of the receiver assembly semi-automatic launch of the structure, only a single launch, magazine slot in front of a non-slip grip with grip, grip with Meg Gepu polymer grip. Insurance, short positions Hanging off the release lever, magazine card shoots are set on both sides of the left and right - many operating components with double-sided design, which is rare in the AR Rifle market, will undoubtedly greatly enhance the robotic ergonomics Very easy to use.
