The Catalyst Arms Hammerhead Bolt Knob

Upgrade your rifle with the Catalyst Arms Hammerhead Bolt Knob. This oversized aluminum bolt knob allows for better control on each shot. 

Its shape allows easy access and prevents the shooter’s hand from slipping onto the bolt handle. This bolt knob will fit all 5/16-24 bolt handles, allowing it to work for most rifles, including RPR and Christensen Arms. 

This bolt knob comes in black, red and sniper grey. If the Hammerhead isn’t the right fit for you, check out Anarchy Outdoors’ bolt knob collection. We have something for everyone.
