These replacement bolt carriers will give your HK-21 a return to glory. Well maintained, with minimal cosmetic wear, they’ll get your gun thumping like new!

The HK21, made by H&K, and their Portuguese subcontractor FMP, was the West German evolution in firearm technology. Designed in conjunction with the MP5 and G3, the most prevalent early buyer was Portugal, who would later buy a license to manufacture the machine guns as well. Much like the G3, it fires NATO’s 7.62 x 51. The HK21s would go on to be used by Portugal until just a few years ago. It’s the bigger brother to an iconic battle rifle, reinforced and updated to serve better as an LMG.
