    MCK Thumb Rest

    Posted by John Cloverfield on 17th Nov 2022

    If you're planning on purchasing an MCK or already have one, then these thumb rests are a must. They improve stability of the firearm by a significant amount. It pairs well with the areas designed for your fingers to seat. The grip of the thumb rest against the grip near the extra magwell, really makes for better performance .

    Thumb rest are good quality and very sturdy. Easy to install but not a must have for added comfort. Feels as comfortable without while handling is it does installed. Im going to keep them installed.

    Makes the Roni so much easier to hold aim and shoot. I think this is the only roni must have accessory sans optic obviously
