MP9 Metal Cylinder Head

Solved the problem of high-speed ammunition feedingA single accessory increases the initial speed--4 meters per second Many product design optimizations:1. Improve the structural strength of the cylinder head itself by changing the material2. Add two airtight O-rings between the push nozzle and the cylinder head3. Independent new mold opening to improve the supply of bombs at high rate of fire4. Increase the flow of push mouth through other methods************************************Since the overall structure of the product is an eccentric special-shaped structure, the processing cost is slightly higher than that of other cylinder heads.************************************This model: the push nozzle enters and exits in the cylinder head, and the movement trajectory will invade the cylinder. Before modification, please make sure that your plan is reasonable. The damage caused by modification mistakes cannot be returned.
