“Pioneer uses old bolt-heads with the hand engraved serial numbers”

All bolt-heads are newly machined and custom fit to each rifle. The laser engraved serial number on each bolt matches the serial number of the firearm. During the assembly process bolt-head is head spaced with the barrel and hand fit with the trunnion. After this operation each bolt-head receives the matching serial number with the gun.

“The bolt heads are old and not blacken”

We blacken not assembled bolt heads only, as soon as they get machined. Then the bolt heads are assembled with the rest of parts (firing pin, extractor, extractors pin and spring) into complete assembly. The complete bolt head assemblies are installed into the firearms. Each firearm is reloaded and dry fired at least 20 times, then it is test fired with the life rounds. During this procedure the blackening on the bolt-head is scratched and has the wear marks. We do not blacken the complete bolt-heads assemblies after the assembly/testing procedure, since the blackening salts may stay in the assembly and will cause continuous efflorescence, which eventually will damage the bolt-head assembly. After testing the bolt-head assemblies are well oiled and protected from the corrosion.
