FPM Gunworks is not a mass-production brand. It is a small, precision-focused manufacturer built around hands-on engineering, iterative testing, and measurable performance.
Suppressors are designed to balance sound suppression, reduced back pressure, durability, and tone — not to chase a single metric at the expense of real-world function. Designs are pressure-tested, metered, and evaluated on both gas and bolt guns, including full-auto platforms. If a design doesn’t perform across realistic firing schedules, it doesn’t ship.
Our suppressors are machined in-house using modern CNC equipment, welded baffle construction, and materials selected for strength and longevity. Design details are protected because they represent years of development and refinement — not for secrecy’s sake.
