Purpose-built for the JK 155HD series of suppressors, this thread mount converts your can to a clean, direct-thread interface—perfect for streamlined builds, dedicated hosts, and shooters who value simple, bomb-proof attachment.

With precision machining for concentricity and a secure shoulder interface, the 155HD Thread Mount helps keep your POI shifts predictable and your range days drama-free.

*Always verify your barrel’s thread pitch and shoulder geometry, and follow the suppressor’s caliber/pressure ratings before use.

Why Choose a Direct-Thread Mount?

Consistency & Confidence

Direct-thread setups minimize interfaces that can loosen or introduce tolerance stack. The result is repeatable mounting and highly predictable point of impact characteristics.

Dedicated-Host Friendly

If you keep your suppressor on one rifle (or rotate among a couple of 1/2x28 hosts), a direct-thread mount is cost-effective and simple, with no need to buy multiple muzzle devices.

Compact Profile

No lugs. No collars. The 155HD Thread Mount preserves your suppressor’s sleek silhouette—handy for vehicles, blinds, and tight barricade work.

Ideal Use Cases

• Hunting & Backcountry: Fewer parts to rattle loose; easy field checks

• Range & Training: Quick install/removal, predictable POI retention

• Suppressed Carbine Builds: Clean, compact attachment on 1/2x28-threaded barrels

• Dedicated Hosts: Keep a JK 155HD set up on your go-to rifle without extra hardware

Installation Tips (Read All Manufacturer Instructions)

1. Confirm Thread Pitch: Verify your barrel is 1/2x28 and has a proper shoulder.

2. Clean Interfaces: Degrease barrel threads and mount threads for best fit.

3. Hand Start, Then Torque: Hand-thread to ensure no cross-threading; torque per the suppressor manufacturer’s guidance.

4. Re-Check After First Use: Heat cycles can settle assemblies; verify tightness and alignment after your first range session.

For hosts with tilting-barrel pistols, use the appropriate piston/booster system instead of a fixed direct-thread mount. Use fixed-barrel spacers or fixed-mount solutions on PCCs or fixed-barrel hosts, as recommended by the suppressor manufacturer.

FAQ

Q: Will this work with any suppressor?
A: It’s designed for JK Armament 155HD suppressors. Check your model’s compatibility before purchase.

Q: Is 1/2x28 right for my rifle?
A: 1/2x28 is common for 5.56/.223 AR-15s and some 9mm carbines. Confirm your barrel’s pitch; many .30-cal rifles use 5/8x24 instead.

Q: Do I need shims or timing?
A: Direct-thread mounts generally do not require timing. Ensure the barrel shoulder is square and the mount seats fully.

Q: Can I use this on a pistol?
A: Tilting-barrel pistols typically need a piston/booster assembly. Use direct-thread on fixed-barrel hosts or as the manufacturer recommends.
