Watchtower Firearms Flat-Faced Comp – 5.56 – Black DLC – 4.0" OAL (CMB556FDLC) – UPC 853810006225

Control recoil, keep your sight picture flat, and sharpen the look of your build. The Watchtower Firearms Flat-Faced 5.56 Compensator features a precision-machined, flat muzzle face and tuned gas ports to help reduce muzzle rise for faster follow-up shots. Measuring a compact 4.0" overall length and finished in ultra-hard black DLC (Diamond-Like Carbon), Model CMB556FDLC (UPC 853810006225) is built to run hard, clean easily, and look phenomenal on any modern 5.56/.223 rifle or AR-15 upper.

Why a flat-faced comp? The squared, flat front and directional porting promote predictable, repeatable muzzle behavior—so your dot or reticle stays on track through rapid strings.

Key Benefits

• Faster splits & better control: Compensator geometry redirects gas to counter muzzle climb, keeping sights flatter between shots.

• Recoil moderation: Reduces perceived recoil impulse for tighter groups in standing, kneeling, and barricade work.

• DLC durability: Black DLC adds outstanding hardness, corrosion resistance, and a low-friction surface that sheds carbon.

• Clean, modern profile: Flat-face styling delivers a purposeful, duty-ready look that pairs with minimalist or full-featured rails.

• Precision fit: Tight-tolerance machining supports concentric alignment to help protect accuracy and minimize POI shift.

Feature Highlights

• Caliber class: 5.56 NATO / .223 Rem

• Overall Length: 4.0 inches

• Finish: Black DLC (Diamond-Like Carbon) for extreme wear and corrosion resistance

• Design: Flat-faced compensator/brake hybrid with tuned porting to counter rise and manage impulse

• Material: Precision-machined steel (DLC-coated)

• Model / SKU: CMB556FDLC

• UPC: 853810006225

Typical 5.56 barrels use 1/2×28 muzzle threads. Always confirm your barrel’s thread pitch and the device’s spec on the package label before installation.

Ideal Use Cases

• Carbine classes & competition: Faster transitions and more consistent sight return under the clock.

• General-purpose & duty builds: Durable finish and predictable handling for high-round-count training.

• Pinned-and-weld projects: The 4.0" OAL may assist certain barrel-length compliance strategies—consult a qualified gunsmith to verify legal overall length and timing.

What You’ll Notice on the Range

• Flatter tracking: Your dot/reticle lifts less and returns faster, especially on lightweight carbines.

• Easier cleanup: DLC’s slick surface resists baked-on carbon, simplifying post-range maintenance.

• Consistent results: Quality machining supports repeatable performance after hard use.

Installation (Quick Start)

1. Verify thread pitch (most 5.56 = 1/2×28) and ensure the shoulder is square and clean.

2. Degrease threads and shoulder; remove old thread locker and carbon.

3. Time the device using the provided shims or a crush washer per the kit instructions so ports index correctly.

4. Torque to spec (per manufacturer guidance), then bore-check for clear, concentric alignment before live fire.

5. For pin & weld, have a qualified gunsmith perform the work and re-verify alignment and legal OAL.

Pro tip: Place a small witness mark across the device and barrel shoulder—if it moves during initial heat cycles, you’ll notice immediately.

Compatibility Notes

• Caliber: Optimized for 5.56/.223 pressures.

• Handguards: Confirm clearance if extending close to or under a rail endcap.

• Suppressors: This is a compensator, not a suppressor mount; do not attach a can unless the suppressor is explicitly designed for over-the-comp use (rare).

• State/Local laws: Some regions regulate muzzle brakes/compensators differently—verify before purchase.

Care & Maintenance

• Post-range cleaning: Let cool, then brush ports and face with nylon/bronze and a carbon-safe solvent.

• Protect the finish: Avoid harsh abrasives; DLC wipes clean easily and resists corrosion.

• Periodic inspection: Check torque, timing, and port edges for debris or impact marks.

Safety & Legal

• Bore alignment matters: If you see any eccentricity or contact marks, do not fire until corrected.

• Compliance: Muzzle-device changes and pin/weld operations can affect firearm classification—follow all federal, state, and local laws.

• Professional help: If unsure about timing, torque, or compliance math, consult a gunsmith.
