Energetic Armament Direct Thread Adapter – 5/8×24 (Barrel) to 1.375×24 (Suppressor/HUB) – Stainless Steel – Black Cerakote® (EA27) – UPC 853406008275

Unlock the modern HUB ecosystem on your 5/8×24 hosts with confidence. The Energetic Armament Direct Thread Adapter (EA27) converts standard 5/8×24 barrel threads to the industry-preferred 1.375×24 (“HUB”) suppressor interface, giving you broad compatibility with today’s most popular modular cans and mounts. Precision-machined from stainless steel and finished in black Cerakote®, the EA27 delivers rugged durability, excellent corrosion resistance, and repeatable alignment—ideal for hunters, precision shooters, and suppressed carbine users who value direct-thread simplicity and return-to-zero consistency.

Why choose HUB (1.375×24)? It’s the most widely adopted universal suppressor rear thread, enabling cross-brand flexibility without locking you into a single mount system—while your rifle keeps its 5/8×24 muzzle.

Key Benefits

• Concentric alignment you can trust: Tight-tolerance machining and a rigid stainless steel body help preserve bore concentricity, reducing the risk of baffle strikes and minimizing POI shift.

• Direct-thread repeatability: Fewer moving parts than QD systems for a lighter, low-profile interface and consistent on/off zero—perfect for precision and hunting applications.

• Built for hard conditions: Stainless steel resists heat, carbon, and corrosion; Cerakote® adds abrasion and chemical protection for long service life.

• HUB versatility: Pair your 5/8×24 host with a wide array of 1.375×24 suppressors and modular rear caps/mounts.

• Balanced design: Compact profile keeps overall length and front-end mass down, preserving rifle handling and harmonics.

Feature Highlights

• Barrel/Muzzle Threads (male): 5/8×24 (RH)

• Suppressor Threads (female): 1.375×24 (HUB pattern)

• Material: Stainless Steel (precision CNC-machined)

• Finish: Black Cerakote® for added weather/solvent/abrasion resistance

• Profile: Compact, weight-conscious direct-thread form factor

• Model / SKU: EA27

• UPC: 853406008275

Always verify your barrel thread pitch (5/8×24 vs 1/2×28, 3/4×24, etc.) before installation.

Ideal Use Cases

• Precision & long-range rifles: Direct-thread consistency for stable dope and minimal shift across remove/replace cycles.

• Hunting rifles: Lightweight, rugged adapter that keeps the rifle lively and reliable in poor weather.

• Suppressed carbines & semi-autos: HUB compatibility without the bulk or complexity of QD devices.

Installation (Quick Start)

1. Confirm thread specs: Barrel 5/8×24 ↔ suppressor/rear mount 1.375×24 (HUB).

2. Prep threads: Degrease all mating threads; inspect shoulder for squareness and debris.

3. Hand-start only: Thread the EA27 onto the barrel by hand to avoid cross-threading, then snug to spec against a true shoulder.

4. Install suppressor: Follow the suppressor manufacturer’s torque and non-permanent, high-temp thread locker guidance (e.g., Rocksett® where appropriate).

5. Bore check: With the bolt removed, visually confirm a clear, centered bore line through the adapter and suppressor.

6. Heat-cycle verify: After initial range time, re-check torque and witness marks for any movement.

Pro Tip: Add a thin witness mark across the adapter and barrel shoulder to quickly detect any rotation during early use.

On-Range Performance You’ll Notice

• Repeatable zero: Direct-thread interfaces are prized for consistent return-to-zero when removing and reinstalling the can.

• Low added mass: Compact stainless body preserves balance and reduces harmonic disruption at the muzzle.

• Rugged longevity: Cerakote + stainless resist baked-on carbon, moisture, and field abuse.

Compatibility Guidance

• Suppressors/Rear Caps: Works with 1.375×24 (HUB) threaded suppressors and many modular systems from leading brands.

• Hosts: Any barrel cut 5/8×24 with a true, square shoulder. This is the most common .30-cal and multi-caliber rifle thread standard.

• Shims/Collars: Use only as directed by the suppressor/device manufacturer; proper shoulder geometry is critical for alignment.

Care & Maintenance

• Post-range cleaning: Allow to cool; brush threads with nylon/bronze and use a carbon-safe solvent.

• Prevent galling: Start clean, dry threads by hand; apply a light oil film for storage.

• Regular inspections: Check for nicks, unusual wear, or carbon locking before the next session.

Responsible Use & Legal

• Know the law: Suppressors and related components may be regulated. Ensure federal, state, and local compliance (NFA where applicable).

• Safety first: Re-check bore alignment whenever you change adapters, mounts, or muzzle devices.

• Gunsmith help: If unsure about shoulder trueness or exact thread spec, consult a qualified gunsmith.
