STEEL Immortal XL AIR Suppressor, 5.45 caliber for AK12 (for standard mount)
The Immortal series of suppressors are professional sound moderators from the STEEL brand, designed for extreme operating conditions. The Immortal XL AIR model is developed for 5.45x39 caliber and the standard AK12 mount; it combines durability, high acoustic efficiency, and the ability to operate in automatic firing mode. These devices demonstrate resistance to intense firing, burst fire, and overheating up to 600°C.
The suppressor is made of Italian stainless gun steel, which provides excellent corrosion resistance. The internal design uses STEEL's patented "floating separator block" technology, which accounts for linear expansion at high temperatures and ensures long-term operation.
Design and Features
At the core of the Immortal XL AIR is a non-disassemblable dual-circuit design with a powder gas deflector and a pre-expansion chamber. The deflector directs gases into two sound moderator circuits, which provides significant shot noise reduction, reduces barrel fouling, and simultaneously performs the function of a muzzle brake-compensator (MBC). The 4th generation floating separator block allows for 70-80% powder gas discharge.
