Benefits

This intermediate sized carbon fibre bolt knob, profesionally designed and made by Lumley, have several benefits:

  • Gain extra leverage for stuck rounds
  • Easier and faster bolt handling
  • Perfect for all weather conditions in wet, heat or cold
  • Super strong and ultra-light weight (0.46oz / 13 grams).
  • Polishing cosmetic scratches possible.
  • Threaded for the common 5/16″ x 24 TPI.

Description

This bolt knob is the result of feedback from many customers over the years wanting a slightly smaller knob but still gain extra leverage and clearance. Therefore this intermediate sized carbon fibre bolt knob design sits in between our tactical and 1″ round options.

The knob includes a recessed end allowing for the bolt to be cycled using just an index finger or thumb for faster and easier bolt handling. In addition this knob will give you more leverage to release stuck rounds in the chamber.

You will get a better grip in all weather conditions because carbon fibre never gets hot and slippery or cold and sticky and is super light.

You will not find a stronger and lighter bolt knob anywhere!

Construction

The design starts at a 0.47″ (12mm) stem diameter. Followed by a concave taper to a 0.75″ (19.05mm) diameter ending with a 1.25″ (31.75mm) overall length. A longer internal thread of 0.7″ allow fitment to a wider range of factory handles as well as our M6 thread adapter. This bolt knob is threaded for the common 5/16″ x 24 TPI.

Material

Lumley makes these bolt knobs from from genuine 3K carbon fiber composite and produces for tight tolerances, concentricity and squareness. That same material is used for expensive automotive parts, aerospace components and racing bikes.

Finish and maintenance

Lumley finishes the carbon fiber to a suitable non-glare matte finish with the basket weave pattern prominent.

To get rid of cosmetic scratches, polish the bolt knob with care and your knob will look like new again. This is an advantage of the carbon fibre material over anodized aluminium which once scratched stays scratched.

Installation

Just screw the bolt knob on to the handle of your rifle.
