JMac Customs RC QD Retainer Cover QD Sling Mount KUSA KP9 MLOK RCQD UPC 850047392113
Product Description
The JMac Customs® RC-QD Retainer Cover & QD Sling Mount (SKU: RCQD / UPC: 850047392113) is a vital ergonomic and structural modernization upgrade engineered for the JMac Modular Mounting System (MMS) on the Kalashnikov USA® KP-9 9mm pistol and KR-9 carbine. When running an MMS handguard equipped with an open sling-loop cutout, shooters often find their support hand exposed to the sharp edges of the factory lower handguard retainer and intense radiative heat escaping from the gas block. The RC-QD resolves both operational issues simultaneously by bridging the open cutout with a smooth, rigid aluminum armor plate.
Precision CNC-machined in the United States from solid billet 7075-T6 aerospace aluminum, the RC-QD provides outstanding structural durability without encumbering your muzzle balance. The component is treated with an abrasion-resistant MIL-A-8625 Type III Class 2 Hardcoat Anodize in matte Black, delivering defense against high operating temperatures, corrosive fouling, gun cleaning bore solvents, and repeated impacts. Bolting rigidly across 1.5 M-LOK slots, this component restores structural rigidity across the handguard's sling-loop window, preventing rail deflection under high-stress weapon manipulations.
Beyond ergonomic heat shielding, the RC-QD features an integrated push-button Quick Detach (QD) sling socket, giving your KP-9 or AK platform a streamlined, snag-free forward sling attachment point. Designed to be completely reversible, the RC-QD can be oriented facing forward or backward on either the left or right side of the forend to accommodate both right-handed and left-handed operators. Additionally, the aggressive forward geometry functions as an impromptu barricade stop, allowing shooters to brace their firearm firmly against door frames, barricade ports, and window ledges for stabilized follow-up shots.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Kalashnikov USA KP-9 / KR-9, AKM, AK-74, and multi-platform rifles running JMac Customs MMS handguards with sling-loop cutouts; universal on any standard M-LOK surface with 1.5 available open slots. CRITICAL staging notice: The RC-QD requires 1.5 consecutive M-LOK slots for proper T-nut engagement. Position the bridge directly over the sling loop window to fully shield your support hand from hot gas block exhaust and sharp retainer hardware. Fastener torque mandate: Do NOT exceed 15 to 20 in-lbs when tightening the steel mounting screws into the M-LOK chassis. Pre-apply medium-strength (blue) threadlocker to the fastener threads to prevent loosening under rapid semi-automatic fire.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty. Field-strip or lock the bolt rearward before commencing forend work.
- Locate the sling-loop cutout on your JMac MMS handguard and verify that 1.5 continuous M-LOK slots are clear and unobstructed by internal gas tube hardware or external accessories.
- Determine desired orientation (sling swivel socket positioned forward or rearward, left-hand or right-hand side) and loosely install the Torx screws and M-LOK T-nuts onto the RC-QD bridge.
- Align the T-nuts parallel to the M-LOK slots, seat the RC-QD flush over the handguard cutout, and apply gentle outward tension while rotating the screws clockwise to engage the T-nuts 90 degrees against the inside handguard wall.
- Torque mounting fasteners to 15 to 20 in-lbs using an armorer torque wrench; insert a standard push-button QD sling swivel to verify positive lockup and 360-degree rotation stops, and confirm zero contact with the barrel or gas block before live-fire staging.
Key Features
- MMS Handguard Sling Loop Bridge: Rigidly covers the factory lower handguard retainer cutout on JMac MMS handguards, restoring handguard structural strength.
- Integrated QD Sling Swivel Socket: Provides a low-profile, snag-free forward attachment point compatible with standard push-button QD sling swivels.
- Billet 7075-T6 Aluminum Construction: CNC-machined from ultra-high-strength 7075-T6 aerospace aluminum to withstand brutal tactical abuse and recoil impulse.
- Advanced Thermal Shielding: Shields the operator's support hand from high radiative barrel heat, hot gas block exhaust, and sharp factory retainer tabs.
- Fully Reversible Ambidextrous Design: Mounts on either the left or right handguard flank and can be staged forward or rearward to suit individual ergonomic preferences.
- Built-In Barricade Stop Geometry: Contoured front profile acts as a positive standoff against barricades, cover ledges, and vehicle frames for steady shot recovery.
- Mil-Spec Type III Hardcoat Anodize: Durable matte Black finish prevents surface wear, chemical corrosion, and field scratching under severe duty conditions.
