G3 Hammer Spring
This is a replacement hammer spring for the HK G3 trigger pack, built to original German military specification. It fits a wide range of HK roller-lock platforms including the G3, HK91, PTR91, HK93, HK33, HK53, and HK21 trigger groups, seating around the hammer spring shank inside the housing. Made from hardened steel, it restores proper hammer tension and cures light primer strikes caused by a fatigued original spring. A smart spare for any G3 or HK91 owner, armorer, or builder who wants to keep a trigger pack running reliably.
