Description
Technical Field
[0001] The utility model relates to the technical field of automatic rifle buffers, in particular to an automatic rifle buffer disassembly tool. Background Art
[0002] The buffer, equipped with a block and spring, prevents the bolt from bouncing during recoil, improving the rifle's reliability and accuracy. However, after prolonged use, damage to the buffer can lead to problems such as premature recoil and misfiring. This is where an automatic rifle buffer removal tool comes in handy.
[0003] However, in actual use of the above-mentioned device, when the buffer is damaged and needs to be disassembled, the remover is generally removed manually. In some guns, the buffer can only be pulled out by dragging the spring. The spring is easily damaged when pulling the buffer, resulting in damage to the buffer. In view of this, we propose an automatic rifle buffer disassembly tool. Utility Model Content
