AB Suppressor Raptor Muzzle Thread Adapter — 1/2x28 to 5/8x24 | 17-4 PH Stainless | Precision Concentric | SKU TA-1/2-28 | UPC 679065311323
Bridge the gap between your barrel and your can—safely and precisely. The AB Suppressor Raptor Muzzle Thread Adapter (1/2"x28 to 5/8"x24) lets you mount Raptor-compatible devices and 5/8x24-threaded muzzle accessories to barrels cut 1/2x28, the most common thread pitch for .223/5.56 platforms. Machined from heat-treated 17-4 PH stainless steel for superior strength, wear resistance, and corrosion protection, this adapter is engineered for concentric alignment and repeatable accuracy when used as directed.

Why Choose the AB Suppressor 1/2x28 → 5/8x24 Adapter?
True Concentricity for Accuracy
Precision internal/external threads and tight runout tolerances help maintain bore alignment, supporting repeatable POI and reducing the risk of baffle contact when installed correctly.
17-4 PH Strength & Longevity
This premium stainless alloy is known for its high tensile strength, excellent hardness after heat treat, and corrosion resistance—ideal for high-temperature, carbon-heavy suppressor use.
Expand Your Options
Run 5/8x24 mounts, brakes, or Raptor interfaces on a 1/2x28 barrel without rethreading or swapping uppers—perfect for multi-rifle suppressor fleets.
Low-Profile, Field-Tough Design
Compact geometry keeps added length and weight down for better handling on carbines and lightweight precision rigs.
Made for Raptor Users
Integrates smoothly with AB Suppressor Raptor systems while staying compatible with many 5/8x24 muzzle devices (always verify manufacturer guidance).
Ideal Use Cases
AR-15/5.56 Platforms: Use a 5/8x24 Raptor mount or brake on your 1/2x28 barrel.
Crossover & Training Carbines: Standardize muzzle devices across rifles with different barrel threads.
Hunting & Field Work: Keep your lightweight rifle nimble while enabling quick suppressor swaps.
Compatibility & Fit Notes
Barrel Thread: 1/2x28 (male on barrel).
Device Thread: 5/8x24 (female on accessory/mount).
Suppressor Family: Works with AB Suppressor Raptor interfaces using 5/8x24, and many 5/8x24 muzzle devices (confirm with the device manufacturer).
Shoulder Requirements: For safe, concentric installation, your barrel must have a proper, square shoulder.
Caliber Considerations: Thread pitch does not equal caliber rating—always ensure your suppressor/muzzle device is rated for your cartridge.
Important: Adapters introduce an additional interface—always check alignment with a rod and follow torque and use instructions from AB Suppressor and your muzzle device maker.
Installation & Best Practices (Overview)
Verify Threads: Confirm your barrel is 1/2x28 and the device is 5/8x24. Inspect threads for burrs/debris.
Clean & Prep: Degrease lightly; apply manufacturer-recommended anti-seize or thread prep if specified.
Torque to Spec: Install the adapter per AB Suppressor torque guidance using a properly fitting tool.
Attach Device: Install your 5/8x24 device to the adapter; time per manufacturer instructions (shims only if specified). Do not use a crush washer unless explicitly recommended.
Alignment Check: Use a suppressor alignment rod before live fire. Re-check after heat cycles.
If unsure, consult a qualified gunsmith. Incorrect installation can cause damage or injury.
Compliance Reminder
NFA/GCA Laws Apply: Suppressors and some muzzle devices are regulated. Follow all federal, state, and local laws for purchase, transfer, and possession.
Safety First: Never fire if you suspect misalignment or damaged threads.

Frequently Asked Questions
Q: Will this work with non-Raptor suppressor mounts?
A: If the mount is 5/8x24 and your barrel is 1/2x28, the adapter provides the thread conversion. Always verify device-specific requirements with the manufacturer.
Q: Do I need shims?
A: Only if the muzzle device maker specifies shims for timing. Most adapters install direct to the shoulder; avoid crush washers unless specifically recommended.
Q: Can I use it on .22 LR or other small calibers?
A: Thread pitch fit is separate from pressure and bore rating. Confirm your suppressor/device rating for the caliber you’ll use.
Q: Will it change my POI?
A: Any added interface can shift POI slightly; this adapter is designed for concentricity and repeatability to keep changes minimal when installed correctly.
