Detachable gun muzzle device

The detachable gun muzzle device comprises a muzzle cap and a muzzle pipe, one end of the muzzle cap is provided with a clamping end, the other end of the muzzle cap is provided with an extension section, the extension section is detachably connected with the muzzle pipe, and the muzzle pipe is provided with an air leakage hole. After a bullet is shot out of a muzzle and enters a muzzle pipe, residual gunpowder gas is guided out through the gas leakage hole in the shooting process, recoil torque of a pistol is counteracted, noise reduction of the muzzle is effectively achieved, time and labor are saved in operation, cost is low, and cost performance is high. 本实用新型采用了一种可拆卸的枪支膛口装置，包括枪口帽和膛口管，枪口帽一端设有卡接端，枪口帽另一端设有延长段，延长段与膛口管可拆卸地连接，膛口管上设有泄气孔，本实用新型通过设置膛口管，膛口管上设有泄气孔，在子弹射出枪口进入膛口管内后，射击过程中将剩余火药燃气通过泄气孔导出，抵消手枪后坐力力矩，有效达到枪口降噪，在操作上省时省力，成本低，性价比高。
