    I really like the heft on this Bolt Knob. It makes throwing the bolt back just that more easy. The size is just right. When you first get your RPR, it looks and feels great, but when you add the upgraded parts from Anarchy Outdoors, now you know that it's all yours!

    I bought this looking to upgrade to my Ruger America. So I bought a new bolt handle and this knob. When I tell you it is a great upgrade and it feels very goood. Easy to grip, and has enough texture to make sure it won't slip. It looks anodized and it might be, but the "Red Color" did not match the Red on my other firearms that have "Red Anodized" parts. I understand the color can be off from one part to another, but this stands out. If you are trying to get it to match items you already have, you may noticed it seem a little brighter than my other part.
    Other than that, I am very happy with it. And would advise it for others.

    Nice big bolt, balanced out the bolt well when coupled with the shroud upgrade. My RPR runs smooth as butter. Quality part with perfect positioning of knurled end not rough at all but a great grip. Anarchy delivers again
