Description
H&K HK21E/23E Inner & Outer Buffer Compression Springs
An unissued set of inner and outer buffer compression springs for your HK21E/23E buffer, sourced directly from HK Germany.
Most HK21E/23E buffers in the U.S are first-generation, which use these exact springs. In contrast, second-generation buffers feature a helical and plate spring column (flat spring), which is not compatible with these replacements. If you’re running a first-gen buffer, these are the correct replacement springs to keep your system functioning properly.
Compatible With:
- HK21E
- HK23E
