The Polite Society Industries Fortitude is a full-size 5.56 NATO suppressor printed in Inconel by laser powder bed fusion, so it holds up to the heat of long strings from a hard-running AR. Its Tripass core sends gas down a central bore and two helical bypass channels into three expansion and mixing chambers, bringing the report down without adding backpressure, and a reduced-backpressure endcap vents gas forward to keep blowback away from the shooter's face.
Internal golf-ball dimpling adds volume and deepens the tone without extra length, keeping the can at 5.00". Fortitude runs the industry-standard HUB interface on a 1.375x24 base and ships with a 1/2x28 direct-thread mount machined from 17-4 stainless with an integrated brake, while integrated wrench flats let a standard wrench handle installation. This is an NFA item.
