Upgrade the control, muzzle rise mitigation, and tactical profile of your .30 caliber AR-platform rifle with the Yankee Hill 3102-1MB-24A Mini Phantom Q.D. Muzzle Brake. Built for shooters who want the benefits of a high-performance brake in a compact, low-profile package, the Mini Phantom combines rugged Melonite steel construction, precision machining, and user-friendly installation to deliver consistent recoil reduction and a professional look on duty rigs and hunting/competition builds alike.

Compact, Effective Muzzle Control

The Mini Phantom Q.D. is engineered to provide meaningful recoil and muzzle-rise reduction without the bulk of full-size muzzle brakes. At just 1.60" overall length, this brake is ideal when you need a short OAL to preserve barrel clearance in suppressor-ready setups or tight handling platforms. Thoughtful porting and internal geometry direct gas laterally and slightly rearward to tame felt recoil and speed follow-up shots, helping you stay on target during rapid strings of fire.

Precision Materials & Finish — Built to Last

Machined from premium Melonite-treated steel, the 3102-1MB-24A offers excellent surface hardness, corrosion resistance, and wear protection. The Melonite process (also known as ferritic nitrocarburizing) produces a durable, low-reflective black surface that stands up to weather, range abrasion, and the demands of frequent use. This finish maintains a tactical, stealthy appearance while protecting critical threads and bore-facing surfaces.

Quick-Detach + Thread Compatibility

This version features 5/8"-24 tpi threads — the industry standard for many .30-caliber and AR-platform barrels — making it a direct fit for compatible barrels and easy to install with standard tools. The compact design also pairs seamlessly with many QD suppressor mounts and adapters for users who want a low-profile brake that doubles as a robust mounting platform for quick-attach suppressors.

• Thread Pitch: 5/8"-24 TPI (check barrel spec to confirm compatibility)

• Overall Length: 1.60" — short, tactical profile for clearances and suppressor co-witnessing

• Caliber: Designed for .30 caliber AR-platform rifles (match to barrel manufacturer recommendations)

Key Benefits & Features

• Compact mini-brake design balances muzzle control with minimal added length.

• Melonite steel construction for exceptional durability, corrosion resistance, and low glare.

• Precision-machined ports reduce recoil and muzzle rise while maintaining a consistent blast profile.

• Standard 5/8"-24 TPI threads for broad compatibility with .30 cal AR barrels and many suppressor mounts.

• 1.60" overall length — ideal for compact builds, suppressed setups, and tight handguard clearances.

• Low-profile aesthetic that complements tactical and precision builds.

• Part Number: 31021MB24A — easy to reference for ordering and compatibility checks.

• UPC: 841812100812

Installation & Use

1. Ensure the rifle is unloaded and the action is open.

2. Verify barrel thread pitch (5/8"-24) and clean threads.

3. Install the muzzle brake by hand-threading onto the barrel until hand tight.

4. Use an appropriate wrench to index and torque according to the manufacturer’s recommendation — typically ensuring proper alignment of the ports and timing of brake orientation. (If you plan to time the brake, use a crush washer, shims, or torque to spec as preferred.)

5. If pairing with a QD suppressor or mount, confirm engagement and lockup per the suppressor manufacturer’s instructions before firing.

6. Perform a function check and confirm there are no baffle strikes with a safe, controlled test firing.

Note: Always follow local laws and manufacturer recommendations when installing muzzle devices and suppressors. If unsure about fitment or timing, consult a qualified gunsmith.

Who It’s For

• Tactical shooters and professionals who need a short, effective muzzle device that won’t interfere with optics or handguards.

• Hunters and precision shooters who want faster follow-up shots and better control without added length.

• Suppressor users seeking a durable, properly threaded brake that pairs with quick-release mounts.

• Builders and AR enthusiasts who prefer a low-profile, durable finish with professional aesthetics.

Compatibility & Fitment Tips

• Designed for .30 caliber AR-platform barrels with 5/8"-24 threads — always confirm your barrel’s thread pitch before ordering.

• Works well on mid-length and carbine-length gas systems; confirm barrel length and gas system geometry for optimal performance.

• If pairing with a suppressor, verify the suppressor’s mount type and clearances; some QD mounts may require specific brake/end-cap geometries.

Care & Maintenance

• Inspect threads regularly for wear; clean and lightly lubricate threads before installation.

• Avoid harsh abrasives on the Melonite finish — a soft brush and solvent will remove fouling without marring the surface.

• Store in a dry environment to prolong finish life; the Melonite treatment greatly improves corrosion resistance but good storage practices extend longevity.
