图为HK公司加装消声器的最新款MR762A1-SD与MR556A1-SD战术步枪,其在老款基础上将护手改成八边形,保留了护手顶部的皮卡汀尼导轨,其余7边均设有导轨安装孔,兼作散热孔,有效减小了护手的质量。其型号名称中,SD代表消声器。为配合护手形状,消声器的外形也被设计为八边形。为方便加工,消声器的形状基本都是圆筒型,鲜见其他形状的消声器,这款消声器显得与众不同。尽管其外形为八边形,但内部仍然采用圆筒形,并且分为两段,较长的后段主要作用是使火药燃气膨胀而降温降压,降低枪口噪声,其内部设有涡流状的导流槽,防止消声器松动;较短的前段主要作用则是进一步降低枪口噪声。这种消声器的消声效果比传统消声器更优。
The photo shows HK’s newly installed MR762A1-SD and MR556A1-SD tactical rifles with mufflers, which changed the hand guard to an octagon based on the older model, retaining the Picatinny rail at the top of the hand guard and remaining seven edges With rail mounting holes, also serve as cooling holes, effectively reducing the quality of the hand guard. In its model name, SD stands for silencer. In line with the hand guard shape, muffler shape is also designed as an octagon. For the convenience of processing, the basic shape of the muffler are cylindrical, rare muffler of other shapes, this muffler looks different. Although its shape is octagonal, but the interior is still cylindrical, and is divided into two sections, the longer the main role of the latter is to make the gunpowder gas expansion and cooling temperature and pressure to reduce the muzzle noise, which is equipped with a vortex Of the diversion groove to prevent the muffler loose; the main role of the shorter front section is to further reduce the muzzle noise. This muffler muffler effect is better than the traditional muffler.
