Catalyst Arms is excited to introduce the Hammerhead bolt knob.  Designed for maximum control and ease of use when working a precision rifle action. The Hammerhead has a “waist” to capture the trigger finger, or edge of the hand, when popping the bolt up for round ejection and chambering.  It also provides extra surface area for a better grip, regardless of how the bolt is cycled. 

The Hammerhead is designed for maximum control and comfort when cycling a bolt action rifle.

The Hammerhead works with bolt handles with 5/16-24TPI threads such as the Ruger Precision Rifle and many others.

Machined from 6061-T6 aluminum and anodized black or red, the Catalyst Arms Hammerhead bolt knob installs without permanent modification to the rifle.  Simply remove the factory bolt knob and replace with the Hammerhead.  MSRP is $34.95 and is now available.  For more information visit
