Our Kestrel Weather Meter Carriers are a must have for any Long Range Precision Shooter. The Carrier has been designed with 2 main tasks, to protect the Kestrel from any bumps, impacts or scrapes and to allow the user to have quick access to the Weather Meter at a moment’s notice. The Carrier uses an MRD (Mag Retention Device) to keep the Kestrel securely in place as well as having the added benefit of adjustable retention.To adjust the retention on the Kestrel Carriers you need to screw or unscrew the silver grub screw found on the side of the carrier with a 1/8” Allen key/hex key.Features:Made of 2mm Thick KydexProtective DesignWater ResistantAdjustable RetentionStops Accidental Button PressingMolle or Belt MountingFitment:Kestrel 4000Kestrel 4000NVKestrel 4500NVKestrel 5000Kestrel 5100Kestrel 5200Kestrel 5500Kestrel 5700Once you have the Carrier set up, we strongly advise using a Threadlock or Loctite to ensure all screws won’t come loose over time and use (even a dab of superglue will do the job!)
