MMS - Rigid Mount - JMac Customs MMS - Rigid Mount - JMac Customs JMac-HF-RM Material: 4140 HT Steel Finish: Black Oxide Set of 2 (one for each side) MMS - Rigid Mount - JMac Customs. The MMS (Modular Mounting System) was designed to allow the user to configure their firearm to fit their needs. The core of the MMS is a lightweight MLOK handguard with a free-float design that allows the user to build upon that with optic mounts, gas tubes, accessories, etc. We’ve continued to innovate and create new options for the MMS and the Rigid Mount is no different.  The MMS Rigid Mount is a fully user-configurable way to add rigidity to the lightweight MMS handguard. The Rigid Mount can be placed anywhere along the barrel using any of the available MLOK slots and creates a fixed mounting position to increase the rigidity of the MMS handguard.
