This article is intended to reveal the clustering structures at the sector based on the level of cooperation among the companies at the Beyşehir Gun Industry Sector. Accordingly, the characteristics of the clusters available at the sector were identified, and an analysis was carried out to find out if there is any difference between the clusters according to the sizes, labors, exportation, shareholding structures and cooperation levels of the business companies. The research data was obtained through face-to-face interviews using a questionnaire consisting of 13 questions. The research applies to 100 business companies located in Beyşehir, where shotguns started to be manufactured in Huğlu in 1962, and today, there are 190 companies registered with the chamber of trade. The clustering potential of the region was revealed with the help of NodeXL, software for network analysis and visualization. The hypotheses were tested with the chi-square independence test through the SPSS packaged software. The analysis indicated that the clustering structure at the Beyşehir Gun Industry Sector is rather regional, and the clustering was intensified in three separate regions: Huğlu, Üzümlü and Beyşehir. In the cluster where there are mainly the companies from the region of Huğlu, the clustering level is high and, the production is based on component manufacturing. There is an intense cooperation between the business companies located in this region, in particular the Huğlu Shotguns Cooperative, and spare part manufacturers, which is the reason why there are many small size house-workshops therein. And in the cluster, where there are mainly the companies from the regions of Üzümlü and Beyşehir, the number of business companies operating in the production of shotguns in larger areas is higher.
