STEEL Immortal Suppressor cal. 5.45/.223. Thread M24x1.5R Long

The Immortal series of suppressors from the STEEL brand are professional sound moderators designed for extreme operating conditions. The Immortal model for.223 Rem (5.56/45) and 5.45x39 calibers is designed for intense, prolonged burst firing, withstands overheating up to 600 degrees Celsius, and demonstrates exceptional resource reliability. The device's design provides sound reduction up to 65% (approximately 28 dB according to a sound level meter), minimizes barrel fouling, and implements the function of a muzzle brake-compensator (MBC).

The suppressor is made of Italian stainless gun steel, which guarantees corrosion resistance and durability. The internal architecture includes the patented "floating separator block" TM STEEL technology, which compensates for linear expansion at high temperatures and ensures stable operation even after intense firing. Inside, a powder gas deflector is installed, directing gases into two sound moderator circuits, which increases acoustic efficiency and reduces recoil.

Key features of the Immortal 5.45 M24x1.5R Long model

• Dimensions: 235×38 mm; total length 235 mm.
• Thread: M24x1.5R Long, designed for installation on AKS/AKSU and compatible platforms.
• Material: Italian stainless gun steel — resistance to corrosion and high temperatures.
• Acoustic efficiency: noise reduction ~28 dB (approximately 65% reduction).
• Chambers: 9+1 design (equivalent to 17 chambers in competitive models), providing compactness and effective sound suppression.
• Construction: non-disassemblable, which increases strength and reliability in field conditions.
• Additional elements: pre-expansion chamber, floating separator block, powder gas deflector, active MBC function.
• Coating: Cerakote firearm paint for additional protection and aesthetic appearance.
• Capable of withstanding automatic firing mode and intensive use.

The Immortal model is optimal for shooters who require a combination of acoustic efficiency, durability, and compatibility with combat platforms. Thanks to the well-thought-out architecture of the internal chambers and deflectors, the suppressor simultaneously acts as a sound moderator and a muzzle brake-compensator, reducing both the sound of the shot and vertical/lateral shifts during firing.

Technical specifications

The STEEL Immortal suppressor is an investment in reliability: proven materials, innovative internal solutions, and a protective Cerakote ceramic coating. The model is ideal for combat and civilian use when it is necessary to combine low noise, reduced barrel fouling, and muzzle impulse compensation. Thanks to the M24x1.5R Long thread, it is easy to install on compatible platforms, and the robust non-disassemblable design ensures long-term operation without additional maintenance.

If you need a reliable sound moderator for AKS/AKSU or compatible 5.6 mm systems, the Immortal model guarantees high performance under intensive use.
