The Seekins Precision Havak Black Melonite Steel muzzle device with 5/8"x24 threads is a precision-engineered component built for shooters who demand reliability and durability in their rifle setup. Seekins Precision is known for manufacturing high-quality AR and bolt-action parts with exacting tolerances, and this muzzle device reflects that commitment. Whether you're setting up a precision rifle, a duty gun, or a hard-use hunting build, a quality muzzle device is foundational—it's what threads your suppressor or brake onto your barrel, so it has to be right.
The black melonite steel construction provides excellent corrosion resistance and durability in harsh field conditions. The 5/8"x24 thread pitch is a standard specification for rifles in common calibers, making this device compatible with a wide range of suppressors, flash hiders, and brakes threaded to that spec. Seekins' manufacturing reputation means you're getting tight tolerances and consistent fit—no rocking or binding when you mount an accessory.
This is a no-frills, no-compromise component for builders and shooters who understand that accuracy and reliability start with the fundamentals. If your rifle needs a new muzzle device or you're building a new upper from the ground up, Seekins delivers the quality that pairs seamlessly with the rest of your precision setup.
| Brand | Seekins Precision |

| Product Type | Muzzle Device / Muzzle Adapter |
| Thread Pitch | 5/8"x24 |
| Material | Black Melonite Steel |
The 5/8"x24 thread pitch is a standard specification for many rifle calibers. Compatibility depends on whether your rifle barrel is threaded to this spec. Common applications include various centerfire rifle calibers, but verify that your barrel has a 5/8"x24 thread pattern before ordering.
This muzzle device is threaded 5/8"x24, which is a standard suppressor mounting interface. Any suppressor or sound moderator with a 5/8"x24 internal thread will mount directly to it.
Seekins Precision manufactures to tight tolerances, ensuring consistent fit and zero rocking when you mount an accessory. The black melonite steel finish provides excellent durability and corrosion resistance. Quality matters when it comes to muzzle devices—a loose or inconsistent fit can degrade accuracy and introduce reliability issues.
Only if your barrel is threaded 5/8"x24. If your rifle has a different thread pitch (like 1/2"x28), this will not fit. Confirm your barrel's thread specification before purchasing.
