Napier SilenSave Moderator Spray is a revolutionary product that every rifle shooter has been waiting for, offering the long-awaited solution to preventing corrosion in gun silencers (also known as sound moderators). Silencers are an essential part of every stalker’s kit, but they are notorious for rusting and corroding over time, which can lead to costly damage to expensive rifles. In fact, many gun owners have horror stories of silencer corrosion rendering their guns unusable. Until now, there has been no effective way to protect these crucial accessories.

SilenSave is the result of Napier’s longest-ever field trial, providing a simple, yet highly effective solution. The chemical is designed to be sprayed directly into both ends of the moderator prior to storage. Once applied, SilenSave creates a fine, even coating on the internal surfaces and baffles of the silencer. The chemical is dispensed with a very low-pressure aerosol, ensuring that it forms a mist that evenly coats the internal parts of the silencer, including hard-to-reach areas. This coating contains Napier’s VP90 corrosion inhibitor and other specially selected compounds, which are carried by a specific solvent that evaporates, leaving just the finest protective layer behind.

The unique aspect of SilenSave is its two-step process. The initial coating protects the silencer during storage, but it is the second stage that sets SilenSave apart from other products on the market. Upon firing the rifle for the first time after application, the extreme heat generated during shooting bonds the chemical to the metal surfaces inside the silencer. The heat essentially forms a protective layer that adheres almost like a ceramic coating, offering long-lasting protection against corrosion. Regular use of SilenSave prevents the silencer’s internal surfaces from corroding and prolongs the life of any type or make of moderator.

While condensation inside a silencer is inevitable, SilenSave ensures that the moisture does not lead to damage over time. The regular application of this innovative product will greatly reduce the risks associated with rust and corrosion, ensuring that your silencer remains in optimal working condition.

Napier has conducted extensive testing over the past 6 years to validate the effectiveness of SilenSave. In one extreme test, a brand-new Jet Z moderator fitted to a Mauser MO3 rifle was used weekly to fire over 500 .308 rounds. After all that use, there was absolutely no sign of internal corrosion. The silencer could still be easily screwed on and off the barrel without any issues, demonstrating that SilenSave provides long-term protection even under demanding conditions.

SilenSave is ideal for anyone who owns or uses a rifle with a silencer. Whether you’re a professional stalker or an avid shooter, this product ensures that your silencer remains corrosion-free and fully functional, regardless of how often you use it. By preventing rust and extending the life of your silencer, SilenSave offers peace of mind and protection for one of the most critical components of your firearm setup.
