Tikka 558 and 658 Bolt Shroud

Fits Tikka models 558 and 658 only

CNC machined from high grade aerospace 7075-T76 alloy and and hard anodized black (milspec type 3). This bolt shroud is a faithful reproduction of the now discontinued factory spare part (Tikka reference: S5840244). We machine the internals to tight tolerances which is instantly apparent by the lack of slop when removing the factory plastic shroud and replacing it with ours. This is not just a decorative part, the shroud is designed to protect the shooter's face in the rare event of a cartridge rupture or failure, where hot gas and powder debris can travel back through the bolt body via the firing pin hole.  Our design is very similar to the factory original part with a few small changes to accommodate the CNC machining required to manufacture them.

Notes

• All shrouds come with a small coil spring which is optional to install. This spring takes up the slack of a necessary tolerance designed into the shroud to ensure proper function of your firing pin assembly across any Tikka Centerfire bolt assembly. Installing the spring will remedy any minor noise made by the shroud in this dimension when out hunting.
  
• Our shrouds are CNC machined to a tolerance within +/- 0.05mm (approx +/- 2 thou) in the critical dimension that locks into the firing pin assembly. This dimension has been cut slightly deeper than required to account for variations discovered between different rifles tested.
