We use OXCREEK TACTICAL molds for all of our vac pressed shells. We use .80 Kydex on a membrane less vac table. Our single mag carrier shells are made to accommodate an MRD on the side of the carrier to allow multiple magazine manufactures to be used by adjusting the MRD. The MRDS can be purchased in the Specialty Attachment section of this site. These shells can be used with multiple types of FOMIS, DCC Monoblock, loops and other IWB attachments.
