Inquiry (采购产品): Stainless blk ox Hi, I have approx 200 stainless D-rings and 12ga hydrocut sling sliders that require a blackened finish, black oxide is preferred. All parts are for rifle slings. Future jobs will be same size or possibly much larger hopefully. We will deliver and pickup. **** Hidden Message ***** Corey Reynolds 32927 Company: Sling Dynamics LLC E-mail: slings@slingtec.com **** Hidden Message ***** slings@slingtec.com
