JK Armament 155HD Thread Mount – 1/2×26 – JK155HDM1236 – UPC 850017729308
Lock in rock-solid, repeatable suppressor alignment with the JK Armament 155HD Thread Mount in 1/2×26. Purpose-built for the JK 155HD modular suppressor system, Model JK155HDM1236 (UPC 850017729308) delivers a simple, lightweight, and highly concentric direct-thread interface that shooters trust for accuracy, reliability, and a compact overall profile. If you prefer direct-thread over QD for its weight savings and return-to-zero consistency, this mount is the right tool for the job.
Why direct-thread for the 155HD? Fewer moving parts means less weight, lower stack height, and repeatable zero when you remove and reinstall your can. It’s a favorite among precision shooters, hunters, and anyone who values consistent POI.
Key Benefits
Concentric, secure interface: Tight-tolerance machining supports true bore alignment, helping protect baffles and minimize POI shift.
Compact & lightweight: Keeps your suppressor setup trim without bulky adapters, ideal for field carry and long training days.
Rugged materials & finish: Precision-machined metal construction with a corrosion-resistant exterior stands up to carbon, heat, and weather.
Fast swap capability: Thread off your existing mount and install this 1/2×26 unit to run additional hosts with the same can.
Clean aesthetic: Low-profile geometry blends seamlessly with the 155HD for a professional look.

Always verify your barrel thread pitch (1/2×26) and that your muzzle shoulder is true and square before installation.
Ideal Use Cases
Precision & hunting rifles/carbines: Direct-thread repeatability supports stable dope and confident cold-bore shots.
Range & training hosts: Lightweight setup that reduces front-end mass and keeps handling lively.
Multi-host shooters: Easily convert additional 1/2×26 barrels to the 155HD ecosystem without re-zeroing a QD device.
Installation (Quick Start)
Confirm compatibility: Barrel 1/2×26 threads; suppressor: JK 155HD.
Prep threads & shoulder: Degrease the barrel threads/shoulder and the mount; remove old carbon or thread compound.
Hand-start only: Thread the mount onto the barrel by hand to prevent cross-threading.
Torque & locker: Follow JK Armament torque guidance. If specified, use a high-temp, non-permanent thread locker (e.g., Rocksett®) per manufacturer instructions.
Bore check: With bolt removed, visually confirm clear, concentric alignment through the mount and suppressor before firing.
Witness mark: Add a small mark across the mount and barrel shoulder to spot any rotation during early heat cycles.
Pro Tip: Re-verify torque and alignment after your first range session or any hard use/heat cycles.
On-Range Advantages
Repeatable zero: Direct-thread design helps your rifle return to zero after removal/installation.
Reduced weight & length: Keeps the system slim for better balance and carry comfort.
Confidence under heat: Properly torqued mounts resist loosening through extended strings.
Care & Maintenance
Post-range: Allow to cool, then break carbon with a nylon/bronze brush and a carbon-safe solvent.
Thread care: Keep threads clean and lightly oiled for storage; avoid abrasive media that can gall mating surfaces.
Routine checks: Inspect for wear, nicks, or carbon locking; re-snug to spec if needed.
Safety & Legal
Bore alignment matters: If you see any eccentricity or contact marks, do not fire until corrected.
Know the law: Suppressor use and transport are regulated—comply with all federal, state, and local regulations (NFA where applicable).
Gunsmithing help: If you’re unsure about shoulder squareness or torque, consult a qualified gunsmith.
