HMB Bolt Knobs

(0 review)


A great upgrade for any of our HMB actions. Featuring a 1/4-28 female thread, this knob can change the feel of your rifle drastically. Improving tactile feeling and overall improvement of ergonomics. 

Installation tip: We use green Loctite to hold the factory knob on. Heat gently with a torch or heat gun and secure the original knob in a vise with padded jaws or similar wrapping to prevent marring. Clean the thread on the bolt stem, add a few drops of thread locking compound to the inside of the new knob and thread on in the same way. It doesn't need to be tightened much. Let it sit, then enjoy the new look and improved feel.
