    Product Details
    (R)ecoil (R)eduction (360)Degree Ports (24)24-1.5RH (F)aceMount (KM)KeyMount

    The RRD-360-24F-KM allows you to attach KeyMount/KeyMicro compatible devices to your 24-1.5RH threaded firearm. Previously, this could only be accomplished by having your firearm re-threaded to accept a standard KeyMo device. In addition to the ability to attach a KeyMo device, the RRD-360-24F-KM has external 1.375-24 threads located at the base which will allow you to attach an extended blast shield in the future. 

    The RRD-360 Muzzle Device from JMAC Customs is unlike others on the market today. This device vents gasses 360 degrees away from your muzzle requiring less effort from the shooter to manage recoil. The use of additional, smaller ports, allows the gasses to disperse in a less concentrated pattern which reduces flash and concussion when compared to a standard muzzle brake. Due to the 360 design, this device does not require timing which makes installation much more simple and does not require shims or crush washer. 

    What makes the 360 unique?

    • 3 baffles to protect your suppressor
    • No timing / shims not required
    • Lightweight
    • Minimal added length
    • Compatible with dozens of suppressors
    • Reduced Recoil

     Specifications:

    • 24-1.5RH Threads
    • Overall Length: 2.91 Inches
    • Lenght Added: 2.08 Inches
    • 10mm Bore
    • KeyMount and KeyMicro Compatible
    • Compatible with the Extended Blast Shield (Coming Soon!)
    • 17-4ph Stainless
    • Black Nitride
    • Not intended or recommend for barrels shorter than 10.5 Inch (see below) 
    When testing these devices, we found that high rates of fire such as full auto or "mag dumps” could cause damage to the device due to the excess heat, pressure, and gasses from unburnt powder on shorter barrels. 

    Keymount Suppressor Compatibility

    JMac Customs is NOT responsible for improper installation of this muzzle device or any damage to the suppressor using this device. We recommend this be professionally installed and checked to ensure alignment.

    JMac Customs recommends that all suppressor mounts be installed and checked for alignment by a certified professional. Serious damage could result to your suppressor/firearm and physical harm is possible if installed/used incorrectly. All suppressor mounts MUST be tight against the shoulder or face of the barrel, using shims or face-milling method. Contact us if you have any questions or need a recommendation for professional installation. JMac Customs LLC is not liable for injury, damage, or death related to the usage of this product.
