JMac Customs QD Sling Mount/Retainer Cover Black. The RC-QD attaches to any MLOK surface and adds a front QD attachment point for your sling and is reversible which allows you to place it in a position thats ergonomic to your hand. In addition to QD sling swivels the RC-QD will also be compatible with most universal sling loop attachments. An additional feature of the RC-QD is that it bridges the gap created by the sling loop cutout on the JMAC MMS Handguard. This increases the rigidity of the handguard out past the sling loop cutout. In addition the RC-QD offers protection for the shooter's hand against heat created by the lower handguard retainer and protruding sling loop on Kalashnikov pattern firearms. We highly recommend that the RC-QD be used with any MMS with a sling loop cutout. The RC-QD's profile also allows it to be used as a standoff between your firearm and surfaces such as barricades. This allows for better control of your firearm and faster follow-up shots when used against a barricade or other similar surface.
