Ambient Arms EXO Suppressor: Revolutionary Cooling Tech at SHOT Show 2026

The core innovation behind the EXO is Ambient Arms' patent-pending Ambient Intake System. Unlike traditional suppressors that only exhaust gas, the EXO features intake ports that actively draw in cold ambient air during the firing cycle.

The technology is inspired by jet engine cooling. As propellant gases launch into the suppressor, they create low-pressure zones that suck in outside air. This ambient air mixes with the hot gases, dramatically reducing internal temperatures.

The suppressor features three distinct intake stages: initial, middle, and final ports. Each stage is designed based on different aerodynamic principles to create optimal low-pressure zones depending on the internal gas dynamics. The result is a device that artificially performs like a much larger suppressor by trapping more air volume than its physical size would normally allow.

The scalloped end-cap design further enhances performance. Inspired by modern jet engine nacelles, these scallops create micro-turbulences that force the pressure wave to collapse on itself, specifically targeting sound reduction at the shooter's ear.

The temperature difference is dramatic. After 30 rounds, a typical suppressor reaches 400-450°F. The EXO maintains approximately 85°F at the front and 150-180°F at the rear. In testing, the front of the suppressor measured as low as 50°F immediately after firing.

This enables what Ambient Arms calls the "touch test": shooters can grab the suppressor immediately after a high-rate magazine dump without burning themselves. With a standard suppressor, this would cause severe burns.

The cooling technology addresses several real-world problems beyond comfort:

• →Reduced Thermal Signature: Night vision and thermal optics won't pick up the suppressor glowing like a beacon after firing. A standard suppressor lights up immediately under thermals.
• →No Heat Mirage: Precision shooters won't see heat shimmer rising from the suppressor, which distorts the sight picture on hot suppressors.
• →Increased Component Life: Lower temperatures mean less thermal stress on barrel, bolt carrier group, and gas rings. The suppressor itself becomes a heat sink, pulling heat out of the barrel rather than adding to it.
• →Tactical Handling: Operators can sling their rifle without burning through gear or injuring a teammate when taking cover.

Beyond cooling, Ambient Arms claims the EXO is their most accurate suppressor design. Instead of traditional baffles, the EXO uses an internal ported barrel that mimics the dynamics of the rifle's actual barrel.

This provides a perfectly symmetrical reflective surface for pressure waves, reducing the micro-turbulences that typically affect bullet flight path as it exits a suppressor. Ambient Arms claims this produces a cleaner launch than even shooting a bare muzzle.

All models are full-auto rated and pass full SOCOM surge testing. Detailed cleaning is recommended every 2,500 rounds. The EXO ships with a 1/2x28 Universal HUB mount included, compatible with various quick-detach and direct-thread options on the market. Coating is C-Series Cerakote in matte black.
