Product Description
ASE UTRA HEAT COVER FOR SL5i SOUND MODERATORS – FDE
The ASE Utra Heat Cover for SL5i Sound Moderators is a purpose-built, high-performance suppressor accessory designed to deliver superior heat protection, mirage reduction, and safe handling for shooters using the SL5 series sound moderators. Manufactured by leading Finnish brand Ase Utra, this heat sleeve is engineered for field, hunting, and sport shooting applications where thermal control directly impacts accuracy and performance.
Constructed from premium 1000D Cordura® combined with heat-resistant Nomex®, the SL5i heat cover provides exceptional durability and reliable thermal insulation under repeated firing conditions. It significantly reduces heat mirage (thermal shimmer) rising from the suppressor, helping maintain a clearer and more stable sight picture when using magnified optics.
Specifically designed for the ASE Utra SL5i Sound Moderator series, this cover ensures a secure and tailored fit for consistent performance in real-world use. It is ideally suited to bolt-action rifle platforms and moderate firing schedules, where it effectively manages suppressor heat without compromising handling balance or weapon control.
In addition to performance benefits, the ASE Utra heat cover enhances user safety and comfort by insulating the suppressor surface and reducing the risk of burns during handling in the field. The rugged Cordura outer layer also helps reduce noise caused by incidental contact with vegetation, clothing, or equipment during movement.
Finished in a durable FDE (Flat Dark Earth) colourway, this version offers a low-profile, practical appearance suitable for both hunting and tactical environments. Lightweight, compact, and highly functional, it is designed for shooters who require reliable thermal protection without unnecessary bulk.
