Owner’s Manual & Safety Information
Suppressor Systems
Read this manual completely before installing, using, removing, cleaning, transporting, or storing your suppressor.
Improper installation, poor alignment, incorrect ammunition, or use on an incompatible firearm may result in suppressor damage, firearm damage, serious injury, or death.
This suppressor is an NFA-regulated item. Possession, transport, transfer, or shipment must comply with all applicable federal, state, and local laws.
One Horse suppressors are lightweight, American-made rifle suppressors engineered to help reduce muzzle blast, flash signature, and sound exposure while maintaining durability, balance, and repeatable performance.
Built from Grade 5 Titanium and designed around a 1.375×24 HUB-compatible rear interface, the One Horse suppressor lineup supports versatile mounting options across compatible host platforms.
A multi-platform .30 caliber suppressor designed for broad caliber compatibility.
A dedicated 5.56 suppressor optimized for modern 5.56 rifle platforms.
Each suppressor package includes:
The OH-Hub Mount is designed to pair with the included Plan B mount for secure attachment and repeatable alignment.

SPECIFICATIONS
Before installing any suppressor, mount, or muzzle device:
Never install or remove a suppressor on a loaded firearm.
Before installation:
Do not proceed if thread condition or alignment is questionable.
One Horse Suppressor Systems require a barrel and mounting setup that provides proper shoulder geometry so the mount can seat squarely and concentrically.
Do not install the suppressor, OH-Hub Mount, or Pike Flash Hider on a barrel that lacks the required shoulder geometry.
Barrels with tapered shoulders are not supported unless an approved adapter or taper cap is installed to create the proper shoulder for the mounting system.
Improper shoulder geometry may cause misalignment, suppressor damage, firearm damage, serious injury, or death. Always verify bore alignment before firing.
Do not exceed recommended torque.
Stop immediately if the suppressor does not thread smoothly or seat fully.
Before live fire on any new host/mount/suppressor setup:
If alignment is uncertain, do not fire. Consult a qualified gunsmith.
During firing sessions:
Use only quality ammunition appropriate for both the firearm and suppressor.
Use only with approved host firearms and compatible mounting systems.
The Ashe and Ryn are built for heavy use and hold up in some of the harshest conditions. That being said, they are not rated for sustained full auto fire.
Suppressor performance varies depending on barrel length, host firearm, caliber, ammunition, mount type, environmental conditions, and test protocol.

Suppressors reduce sound exposure, but they do not eliminate all report or impulse noise.
Always wear hearing protection.
Before handling, ensure the suppressor has cooled fully.
To help prevent accidental burns, use a compatible suppressor heat guard and heat-resistant gloves when handling a recently fired suppressor.
Ensure the heat guard is correctly sized and used within the manufacturer’s stated temperature and firing-rate limits. A heat guard may also help reduce heat mirage and incidental heat transfer to gear.
A Sukon™ Performance heat cover helps reduce heat mirage in your sight picture and protects against accidental contact with a hot suppressor.
Carbon and fouling inside the suppressor may be cleaned using a suppressor-safe immersion cleaner or carbon solvent tank, provided the cleaning solution is verified as compatible with the suppressor’s materials and finish.
Follow the cleaner manufacturer’s instructions for soak time, rinsing, drying, and post-cleaning handling. Do not use any cleaning method that may damage titanium, Cerakote, threads, or mounting surfaces.
If compatibility with the suppressor finish is unknown, test in a small area or contact One Horse before use.
A suppressor-safe immersion cleaner may be used to help loosen internal carbon buildup on the suppressor interior and baffle surfaces.
Always confirm chemical compatibility with titanium and Cerakote-finished components before extended soaking. Avoid aggressive cleaning methods or any tool that may damage threads, bore surfaces, or alignment features.
To help reduce carbon lock:
Do not over-apply lubricant or anti-seize
Do not allow excess compound to enter the bore path or other critical alignment surfaces
Keep any moving interface area clean and lightly lubricated as appropriate for the mounting system design
Not all suppressors, finishes, or mount systems tolerate the same cleaning methods. Do not use ultrasonic cleaning, immersion cleaning, or aggressive solvents unless the method is confirmed compatible with the suppressor’s materials, finish, and construction.
Do not attempt unauthorized modification or disassembly.
Suppressors become extremely hot during and after firing. Contact may cause severe burns. Allow adequate cooling time before handling.
Use only the correct caliber and compatible ammunition for both the suppressor and firearm. Improper ammunition may damage the suppressor or firearm and may result in injury.
Improper threading, damaged barrel shoulders, poor concentricity, debris, or incompatible mounts may cause baffle strikes or end-cap strikes.
One Horse Suppressor Systems are compatible only with barrels and mounting setups that provide proper shoulder geometry for safe mount seating and alignment. Do not use on tapered-shoulder barrels unless an approved adapter or taper cap is installed to create the proper shoulder.
Failure to use the correct shoulder geometry may result in baffle strikes, firearm damage, suppressor damage, serious injury, or death.
Suppressors reduce sound but do not eliminate it. Always wear appropriate eye and hearing protection.
Always verify the firearm is unloaded before installing, removing, or inspecting the suppressor, mount, or muzzle device.
Do not continue use if the suppressor loosens, becomes misaligned, or shows signs of damage.
Suppressors are regulated items. Possession, transfer, and shipment must comply with all applicable laws.
Suppressor laws are changing constantly. Repair or warranty service on suppressors not registered on a Form 4 may be restricted, or may not be allowed to ship, depending on current federal and state law.
For service questions, contact customerservice@theonehorse.com. Availability of repair or warranty service depends on current federal and state law.
DO NOT ship a suppressor without prior authorization.
Because the suppressor is an NFA-regulated item, unauthorized shipment may violate federal law.
