NEW from Faxon Firearms comes the HARMONIX line of suppressors! Announced at SHOT 2025, this new line of 3D printed suppressors offer unique internal design for maximum performance at an impressive price. HARMONIX Sentry Built from aerospace-grade Haynes 282, a high-performance nickel superalloy known for thermal stability and strength under sustained fire. HARMONIX ION Constructed from ultra-lightweight Grade 5 titanium, offering a low-mass option for shooters who prioritize maneuverability and weight savings. Both models are available in: .36 caliber: compatible with subsonic .300 BLK up through 8.6 BLK and .338 projectiles .30 caliber: optimized for traditional precision rifle cartridges 5.56 dedicated: tuned for gas efficiency on carbines and SPR-style setups Each suppressor ships with a direct-thread mount and is HUB-compatible out of the box, making them adaptable to most modern mounting systems. The HARMONIX suppressors are fully 3D-printed, allowing the Faxon team to work around the manufacturing constraints of traditional welding and CNC machining. The result: internal geometries aimed at reducing backpressure, optimizing flow, and maintaining solid sound suppression across calibers. “I’m incredibly proud of the time, effort, and attention to detail the team poured into this project,” said Joey O’Gara, CEO of Faxon Firearms. “After countless hours of testing and design refinement, they truly stepped up—and the final product is a testament to their dedication and hands-on commitment.” That design process meant running dozens of prototypes, many of which couldn’t be machined or welded, to test theoretical performance in the real world. “We tried dozens of concepts, impossible to machine or weld,” said Aaron Meidinger, Design Engineer. “Rigorous testing stripped away all gimmicks, leaving behind purpose-built geometries that play nice with your rifle, your ears, and your budget.” Suppressor design usually forces shooters to choose between noise reduction, weight, backpressure, and cost. Faxon claims HARMONIX aims to cover more ground than typical offerings. “Suppressor design is a balancing act and usually requires compromises,” said Jay Wilson, Director of Product Management. “Sound reduction, flow—backpressure and cleanliness, weight, price. You need to choose between a number of priorities. On HARMONIX, we tried to prioritize it all, and I think these cans deliver.” MSRP: Harmonix Ion $975, Harmonix Sentry $1,100 Why you can trust RECOIL Since our founding in 2012, RECOIL remains the premier firearms lifestyle publication for the modern shooting enthusiast.
