STEEL Immortal XL AIR Suppressor cal..308 (7.62 mm) — Thread 5/8"-24 UNEF

The Immortal series of suppressors from the STEEL brand are professional sound moderators designed for maximum service life and reliability. The Immortal XL AIR is engineered for intensive shooting: prolonged burst firing, automatic mode operation, and overheating up to 600 °C do not affect its performance. This suppressor is ideal for those who require stable operation in the harshest conditions.

The body is made of corrosion-resistant Italian stainless gun steel. The internal design is built using STEEL's patented "floating separator block" technology, which compensates for linear expansion at high temperatures. Inside, a powder gas deflector is installed, directing gases into two sound moderator circuits, reducing the sound of the shot, minimizing barrel fouling, and acting as a muzzle brake-compensator (MBC).
