A variation of the Lumley tactical bolt knob for the operator who wants to have their rifle bolt double as a glass-breaking hammer. With many jurisdictions requiring your bolt to be transported separately from the rifle, this makes a handy backup tool for those unforeseen situations or otherwise for helping your buddy liberate his keys from his locked car.  Suitable for most bolt action rifle platforms with a one-piece bolt or where the handle is welded on, slotted in, or screw fastened. Lumley does not recommend the use on handles that have been brazed onto the bolt body. Like the Lumley anodized Alloy Tactical Knob, the design is made from the best T76 member for the base and cap of the knob which is then mil-spec hard coat anodized (type 3) for durability. the glass breaking tip is tungsten carbide which is secured by an A2 stainless steel nut that has been DLC coated black. The threads are 5/16"x24 TPI and 3/4" (19.05mm) deep so it will shoulder up against every type of handle Lumley has come across. There are 21 small bullnose flutes onto the knob cap to provide a tactile grip for rapid removal in all conditions. The design of the knob base incorporates a set screw enabling the knob to be secured tightly on the bolt handle (optional).

Features:

  • 7075 T76 body, Tungsten carbide tip, Stainless Steel retaining nut
  • Matte black alloy parts hard anodized. DLC coated retaining nut
  • 5/16"x24 TPI (5/16 UNF) - fits most American bolt handles with a threaded end
  • Thread length 3/4" (19.05 mm)
  • Dimensions: 1.35" long, 1" wide at the top, and 0.45" wide at the base
  • Hardness (alloy knob): 150 Brinell
  • Hardness (Tungsten carbide tip): 2600 Vickers minimum
  • Weight: 1.57 oz (38.2 gm)
  • Environmental: chemically stable, UV stable, solvent resistant and corrosion resistant 

Fitting Guide: The glass-breaking bolt knob will fit any bolt handle with a male 5/16"x24 TPI thread and a threaded stem up to 3/4" (19.05mm) in length. The set screw (grub screw) pre-installed into the lower end of the knob is optional however Lumley highly recommends that this is retained and fastened tightly once the knob is installed to the bolt handle. Tightening this grub screw enables reliable removal of the end cap and access to the carbide tip in all conditions, keeping in mind that the use of this glass-breaking knob may be in situations requiring rapid removal and/or under duress. A 2mm metrix hex key is required to tighten and untighten the metric grub screw. Should you have difficulty installing the knob, check to make sure the grub screw is wound out sufficiently to clear the bolt handle threads before tightening.
