Problems and drawbacks

The original assembly has the following disadvantages:

  • the complexity of the manual assembly (50 parts);
  • heavy weight;
  • low efficiency;
  • necessity of periodic internal parts replacement.


  • reduce the labor intensity of production
  • reduce the amount of noise and visible muzzle flash generated by firing;
  • consider the use of cartridges of various calibers.


  • supperssor parts consolidated into a single complex;
  • eliminating manual assembly;
  • reducing the weight;
  • designed complex internal passages and chambers to improve the effectiveness.

SLM technology (Selective Laser Melting) was used for manufacturing. The material taken is stainless steel, production time is 4 days.
