7-Minute Cooling Cycle: Active "turbocharger" impeller forces ambient air through the bore, slashing wait times between shot strings.
Preserve Barrel Life: Prevents the rapid throat erosion caused by shooting high-velocity calibers (like 6.5 CM or .338) through an overheated barrel.
Built-in 50-Micron Filter: Unlike DIY fans, the RifleKuhl filters out range dust and abrasive particles before they enter your precision bore.
Dual-Purpose Safety: The bright red chassis serves as an NRA-approved chamber flag, meeting UK range safety requirements for all club competitions.
Precision Magnetic Sealing: A powerful neodymium magnet secures the unit to your action, while the retractable nozzle creates an airtight seal for maximum CFM efficiency.
Precision rifle barrels are an investment, and heat is their primary enemy. When shooting intensive strings, barrel temperatures can soar, leading to accelerated throat erosion and wandering groups. While competitors like the Sportsman Gun Centre often mention "faster cooling," the MagnetoSpeed RifleKuhl provides a scientific solution. By utilising a high-static pressure impeller—inspired by turbocharger technology—this device forces consistent, filtered air directly through the rifling, bringing a hot barrel down to ambient temperature in roughly seven minutes.
The RifleKuhl isn't just a fan it’s a critical piece of range kit. The retractable nozzle is spring-loaded and designed to fit everything from .22LR to .338 Lapua Magnum. Once inserted, a strong neodymium magnet locks the housing against your steel receiver, ensuring the airflow is directed down the bore rather than escaping through the ejection port. Crucially for UK shooters, the red body serves as a high-visibility chamber flag, allowing you to cool your rifle while remaining fully compliant with range safety protocols.
A major flaw in generic barrel coolers is the ingestion of grit. Using a standard fan at a dusty range can actually damage your bore by blowing abrasive particulates into the chamber. MagnetoSpeed solves this with an integrated, replaceable 50-micron air filter. This ensures that the air reaching your crown and lands is clean, preserving the mechanical accuracy of your rifle. Powered by a single CR123A battery, the unit is compact enough to live in a jacket pocket or range bag, making it the ultimate tool for F-Class, PRS, and load development sessions.
