Testing, Design, Analysis and Prototyping

Stress Outdoor® has a broad range of experience grounded in the design, analysis and testing of civilian and military firearms and firearm sub-systems. This work includes design and analysis involving gas dynamics, mechanisms analysis and the optimization of fire control systems. From shotguns and handguns to aircraft mounted Gatling guns, fully automatic machine guns, suppressors, custom guns and ground based cannons, Stress Outdoor brings a level of depth to the development of new firearms, or solutions to performance and failure problems on existing product platforms that is unsurpassed. With direct access to three (outdoor) shooting ranges at our immediate disposal, we are able to field test instrumented long guns and hand guns in a safe and controlled environment.

Managing the flow of gas is an important aspect of firearm performance. Compensator design is one area where Stress Outdoor has applied the latest computer-based simulation tools to predict the functional performance of various design concepts, rather than resort to endless trial and error prototyping with little or no quantitative understanding of the performance differences.

SES Outdoor offers the firearms industry custom design and prototyping services. Prototyping is accomplished via a network of partnerships with local machine shops, tool builders and molders. Our prototyping experience includes:

  • Injection Molding
  • CNC Machining
  • EDM (wire and RAM)
  • Rapid prototyping
  • Direct Metal Laser Sintering, SLS/SLA
  • Investment Casting
