Rock Solid Industries Aluminum Tactical Bolt Knob is custom machined right here in the USA and will fit your Mosin Nagant or any other rifle that has a standard 5/16 – 24 thread on its bolt handle.
Machined from a solid 6061 aluminum the product dimensions are 2? long with a diameter of 13/16? inches. Our Tactical Knob is very comfortable to use and features RSI’s “Tactical Spiral” pattern. The knob also comes with rubber O rings installed to aid in comfort and control.
This Tactical Bolt knob is the perfect match for our new RSI threaded bolt handle and firing pin spring (each sold separately).
