Jaeger Precision discusses the next round of testing for their STFU airsoft suppressor, aiming to find the quietest internal configuration. He shows seven of eight test units, which modify the standard foam baffle setup by varying the number of chambers, their size, and their arrangement. A final test will alternate foam baffles with hard plastic discs to see if material changes affect sound. The results will influence the design of the next STFU batch, which is planned to be more tracer-friendly, feature revised front geometry to eliminate a "loudener" effect on high-joule setups, and include a forthcoming mini version for integral suppression.
