Faxon Ion & CoreSync Suppressors: 3D-Printed Titanium at SHOT Show 2026

The Ion suppressor represents Faxon's entry into the high-end titanium market. Using 3D-printed Grade 5 titanium, the Ion weighs under 8 ounces while maintaining full rifle caliber capability.

The Ion shares internal baffle architecture with the CoreSync, optimized to balance suppression performance with low backpressure. Both suppressors were teased at last year's SHOT Show and are now shipping to dealers.

The titanium construction makes the Ion ideal for lightweight builds and standard shooting schedules. For sustained full-auto fire, Faxon recommends the Harmonix Haynes with its high-nickel superalloy construction.

The CoreSync represents Faxon's take on modular suppressor design. The outer tube is the serialized component, meaning users can swap caliber-specific cores without additional NFA paperwork.

The practical advantage: buy one serialized tube, then purchase additional cores for different caliber hosts. A baffle strike or squib typically damages only the core, which Faxon can replace without involving the ATF, since the outer tube remains intact.

For users running high-volume fire schedules or transferable machine guns, the Harmonix Haynes uses Haynes 282, a high-nickel superalloy developed for jet engine turbines. The material stands up to extreme heat far better than titanium.

The heat management difference is significant. Titanium suppressors under sustained fire can see rapid erosion at the blast baffle. Haynes 282 maintains structural integrity through firing schedules that would compromise lighter materials.

Faxon is also researching hybrid designs: 3D-printed titanium bodies with Inconel inserts at the initial blast baffle position. This preserves the weight benefits of titanium while protecting the most heat-critical component.

Carbon lockup is suppressor maintenance's biggest headache. Carbon deposits seal the core to the outer tube over time, and traditional solutions involve brass rods, mallets, and freezer tricks. Faxon built mechanical solutions directly into the CoreSync design.

The core features small protrusions, which Faxon calls "windshield wipers," that scrape carbon from the inner tube wall during removal. If carbon has seized the core, the front features a 1/2-inch drive inlet for a standard socket wrench. Users can simply ratchet the core out rather than resorting to impact tools.

The MuzLok system addresses muzzle device timing, the bane of every AR owner who's stacked crush washers trying to get their brake oriented correctly.

The dual-thread design uses standard right-hand threads for the device itself, paired with a reverse-threaded jam nut. This allows perfect timing at any position without shims or crush washers. The reverse threads lock against the forward threads for a secure installation.

Faxon also offers Plan B compatible versions for users wanting to run their suppressors on other mounting systems.

Faxon's rimfire offering takes a different approach with user-tunable internals. The .22 can uses modular baffles in both perforated and non-perforated configurations.

Perforated baffles allow gas to bleed through, reducing back pressure at the cost of slightly higher sound signature. Non-perforated baffles maximize suppression but increase backpressure. Users can mix configurations to tune for their specific host and preferences.

The .22 can carries a full-auto rating up to 5.7x28mm, making it suitable for P90s and Ruger-57s in addition to standard rimfire hosts.

The Ion and Ion X series remain Faxon's flagship lightweight AR-15 builds, targeting the sub-5lb threshold. For 2026, the line adds .300 Blackout to the caliber options.

The Ion X takes weight reduction further with intentional skeletonizing throughout the receiver set and deletion of the forward assist. The slimline muzzle devices are designed to allow the gas block to slide over them, enabling barrel maintenance without removing the muzzle device.

Faxon is reorganizing their complete AR-15 and upper receiver lineup into three distinct tiers: Sport, Pro, and Premiere. The Ion series remains separate as a weight-focused specialty line.

The Sport tier provides an entry point for buyers who want Faxon quality without premium accessories. All tiers use Faxon-manufactured barrels and receivers, maintaining quality parity on the core components while differentiating on furniture and features.

The Premiere tier targets short-barreled .300 Blackout builds with 1:5 twist rates optimized for heavier subsonic projectiles, lightweight bolt carrier groups with mass removed from the rear, and high-end finishes throughout.

Faxon outlined several products in development for later in 2026:

• →Basilisk QD: Quick-detach mounting system targeting Q3 2026, using machine-tool-inspired offsetting tapers for rock-solid lockup with half-turn attachment
• →46-Caliber Suppressor: Dedicated large-bore option
• →Dedicated Pistol Can: Purpose-built handgun suppressor
• →Titanium + Inconel Hybrid: 3D-printed titanium with Inconel blast baffle inserts for improved longevity

The Basilisk QD prototype on display showed promising results. The offsetting taper design, borrowed from industrial machine tooling, aims to eliminate the play found in some quick-attach systems while maintaining true single-motion attachment.
