The alphanumeric code "9780Z5" is not random. Industry insiders point to the "Z5" suffix as an indicator of a zirconium-based surface treatment on critical wear points. Unlike standard phosphate or even standard nitride coatings, the Z5 process creates a ceramic-like hardness on the bolt lugs, cam pin, and firing pin channel. | Issue | Fix / Improvement | |--------|------------------|
