Geco

Behind every success story is an innovative and active founding spirit! Today, GECO can look back on more than 130 years of expertise in the field of sporting and hunting ammunition. A time in which a small trader with a start-up mentality unerringly became a world-renowned brand.

GECO has epitomised innovative development and growth since the company was founded by Gustav Genschow back in 1887. What began as a wholesaler for firearms and ammunition quickly evolved into a flourishing business. Today, GECO ammunition is manufactured according to the strictest quality controls at sites in Germany, Switzerland, Sweden and Hungary.

Our patron, Genschow, would no doubt be proud – and rightly so. His guiding principle of “quality products in the service of hunting and sport” remains firmly embedded in the brand’s DNA. GECO is the brand that inspires and gives confidence to both young and experienced hunters and marksmen.
