    A must have if you run several QD mounts on different rifles. Protects them well.

    Fits perfectly and snug on my QD mount. Looks great too. I also like the texture for easy application and removal.

    Excellent device. Great for use if you run a suppressor on multiple rifles and want to keep the threads for the muzzle devices of the "off" rifles safe. I use it for Muzzle devices with QD threads for the Turbo T2.
