Ase Utra S Series SL7i Suppressor .300 / .338

High-performance suppressor for powerful magnum calibers

The Ase Utra S Series SL7i Suppressor .300 / .338 is designed for users seeking maximum sound suppression with high-energy calibers. As an updated and lightened version of the S7, it delivers an excellent balance of performance, durability and efficiency.

Optimized for magnum platforms

Designed for .300 and .338 calibers, the SL7i is ideal for demanding applications with higher energy levels.

High suppression for powerful calibers

Sound reduction reaches up to 30–33 dB (1 m left of the muzzle) and 26–28 dB at the shooter’s ear (reference values .308 Win), significantly reducing overall sound signature.

Durable stainless steel construction

Manufactured from 300 series stainless steel and fully welded, the suppressor ensures exceptional durability and long service life.

Balanced size-to-performance ratio

Adding only 147 mm to the weapon length, the SL7i maintains a strong balance between suppression performance and handling, even for larger calibers.

Mounting options

The SL7i is available with multiple mounting configurations:

BoreLock: Mounts on compatible Bird Cage or Hiper-S muzzle devices and muzzle brakes
Direct thread: Traditional thread-on mounting
