Area 419 Bolt Knob Features The Area 419 Bolt Knob is machined from aluminum and finished in a hardcoat anodized black coating that resists wear and corrosion through repeated bolt cycling. Built specifically to thread onto Defiance Tenacity and Elite actions with a 5/16x24 thread pattern it gives shooters a drop in upgrade without modifying the action itself. The larger surface area of the knob compared to a factory bolt handle makes rapid bolt manipulation easier under time pressure whether on a competition clock or working a follow up shot in the field. At 1.63 inches in length the knob sits comfortably under the fingers without catching on gear or a scope s ocular bell during cycling. Weighing just 0.2 pounds the Area 419 Bolt Knob adds grip and control without meaningfully shifting the balance of a precision rifle build. Because it is purpose built for Defiance actions installation is straightforward and the fit is precise rather than approximate. Precision rifle shooters often treat the bolt knob as one of the first upgrades on a custom action since it directly affects how quickly and confidently a shooter can run the bolt between shots. The Area 419 Bolt Knob is available for sale at GrabAGun for shooters finishing out a Defiance action build with a purpose matched component.
