Origin/Tl3/Sr3 Replacement Bolt Heads - Standard (0.478'''') Right Hand Bolt Head

One of the highlighted features of the Zermatt Arms Origin, TL3 and SR3 actions is the inclusion of a floating, replaceable bolt head. This innovative design allows users to change out the calibers on their receiver with a simple barrel, bolt-head swap. To facilitate this quick-change capability, Zermatt Arms offers replacement bolt heads in .223 Rem, Standard (.308 Win.) and Magnum bolt heads. Mfg: Zermatt Arms
