Mountain Tactical, located in Bozeman Montana, is a small machine shop committed to producing high quality after market parts for Tikka rifles. This particular bolt handle features a stem which is made from high quality stainless steel and features a natural finish. While the bolt knob itself is made from aluminum and features a hard coat anodized matte black finish. It is worth mentioning that the stem is threaded 5/16x24, which is an industry standard should you decide to change to a different Mountain Tactical knob, or perhaps one of the other manufacturers on the market today.
