The Mountain Tactical Billet Bolt Shroud for Tikka rifle systems, the result of years of meticulous design, testing, and improvement. This bolt shroud is engineered to replace the factory-issued part with a more durable and precision-enhancing component, ensuring your rifle performs at its best. FeaturesThe outside diameter of the Mountain Tactical Bolt Shroud is precisely matched to the inside diameter of the bolt race. This perfect alignment ensures enhanced concentricity of the cartridge to the chamber, similar to the benefit of having a three-lug bolt for optimal alignment to the axis of the bore.Beyond its functional benefits, this bolt shroud adds a sleek and professional look to your rifle, enhancing its overall aesthetic appeal.Constructed from 6061-T6 billet aluminum, this bolt shroud is significantly more durable than the factory plastic shroud shipped with the original Tikka T3 and lighter than the metal injection molded shroud of the T3x.
