Magnetic Particle Inspected (MPI) for Safety & Durability
Each bolt undergoes MPI quality control to detect surface and near-surface defects that ordinary inspections can miss. This non-destructive testing step ensures the bolt meets stringent safety and reliability standards before it reaches your rifle. The MPI process helps prevent catastrophic failures and extends service life under high-stress use.
Complete Firing Pin Set & Precision Fit
The kit includes a hardened 7.62 bolt, matched firing pin, cam pin, and extractor (where applicable), all finished and assembled to proper tolerances. The firing pin is hardened and polished for consistent primer strikes and reduced wear. The extractor provides reliable extraction and ejection for a wide range of .308/7.62 loads.
