    Well built and threaded cleanly. Not useful for a CZ 455. The lack taper makes it hit the ocular bell.

    Installed the Hammerhead on a Ruger Precision Rifle and it is a big improvement over the OEM knob. My hand was prone to slipping off of the original part particularly when my hand was wet. With the Hammerhead, slipping has been eliminated and cycling the bolt is much easier and faster. I am very pleased with the Hammerhead bolt knob and the way it performs. I highly recommend it.

  • Excellent bolt knob

    A perfect upgrade for function and appearance. I chose the Red to match my mag release extension and safety selector. It is large enough to ease manipulating the bolt but not so large it looks like a tumor hanging off the receiver. It is light enough not to make lifting the handle or holding the gun unbalanced.
    If you’re looking for an upgrade from stock or just looking to replace what you already have you can’t go wrong with this knob.
