The Multi-Platform suppressor is a design that is meant to bridge the gap in the suppressor market by being compatible and configurable with both rifle and pistol platform firearms. In the specific design and prototype referenced in this report, the Multi-Platform suppressor was designed to be used with 9mm pistol and 5.56x45mm rifle calibers with safety, effectiveness, and practicality in mind. To achieve this, the suppressor is configurable, utilizing a Nielsen device in the pistol configuration and a solid mount adapter that replaces the Nielson device piston and spring while in the rifle configuration. This allows the suppressor to retain functionality and reliability when setup for either platform. A unique internal baffle design optimizes the suppression capabilities of the suppressor allowing for notable suppression of both calibers for which it was designed. Data collected through live prototype testing proved the Multi-Platform suppressor was able to exceed the original design criteria and reduce the sound pressure levels of the 9mm handgun down to an average of 117.1 dB, approximately a 48 dB reduction over an unsuppressed 9mm handgun, and a 5.56x45mm rifle down to an average of 134.6 dB, just over a 33 dB reduction compared to an unsuppressed 5.56x45mm rifle. The suppressor proved to be reliable through endurance testing and was able to achieve many of the goals and specifications set at the start of this project.
