ふゆふれ@浮遊物 gets an interview with the owner of Material Custom, a specialty shop for DAS airsoft guns. He discusses the shop's services, including sales, maintenance, repair, and custom parts development. The owner explains that he chose to specialize in DAS guns due to their unique combination of electric gun stability and realistic gas blowback recoil, and he started the shop to address the lack of specialized help for common issues with these guns.
