This is an ideal knob for PRS competition rifles where fast bolt cycling and scope clearance are critical. The knob starts at a 0.47" stem diameter then has a concave taper to a 0.75" diameter end with a 1.25" overall length. This design is a result of feedback from many customers over the years wanting a slightly smaller knob but still gain extra leverage and clearance. The design includes a recessed end allowing for the bolt to be cycled using just an index finger or thumb. A longer internal thread of 0.7" allow fitment to a wider range of factory handles as well as the Lumley M6 adapter. Threaded for the common 5/16" x 24 TPI and CNC turned from aerospace-grade 5 Titanium Alloy with an extremely tough and scratch-resistant DLC black coating applied (PVD).
You will not find a stronger and lighter bolt knob anywhere!
