Die Free Co Quick Stop M-LOK QD Sling Cup & Barricade Stop Black The Die Free Co Quick Stop M-LOK QD Sling Cup & Barricade Stop Black combines an M-LOK-mounted quick-detach sling cup with a compact hasty barricade stop. Die Free Co designed the Quick Stop to provide a sling attachment point and a durable support surface in one low-profile steel component. This listing is for the Black model, distributor SKU QUICK-STOP-BLK, UPC 850079932067. The official manufacturer specifications identify steel construction, a Melonite QPQ finish, M-LOK compatibility, and U.S. manufacture. The shape has a natural anti-rotational property and can also be paired with Die Free Co D-NUTs for compatible Q-Sert handguards. Add a QD sling point and compact barricade contact surface to a compatible rail. Verify the mounting interface and order the Quick Stop at BattleHawk Armory. Integrated QD Sling Cup The Quick Stop accepts a compatible quick-detach sling swivel, allowing the user to place a sling attachment point directly on an M-LOK handguard. Sling placement affects how a firearm carries, transitions, and rests against the body, so the mounting position should be selected with the full sling system in mind. After installation, insert the QD swivel and pull firmly in multiple directions to confirm engagement. Check for unintended release, excessive movement, or interference with nearby accessories. QD swivels and sling hardware should be inspected periodically for wear. Hasty Barricade Stop Function The steel body can serve as a compact contact point against an appropriate support surface. This allows the shooter to establish a repeatable interface without relying on the handguard or other sensitive accessories as the primary contact point. The Quick Stop's natural anti-rotational geometry is intended to help it remain oriented under load. Use barricade support only in a safe training environment and avoid placing excessive side load on the handguard. Confirm that the accessory remains secure after repeated contact or hard use.

Confirm available M-LOK slot space, screw length, barrel and gas-system clearance, and the orientation needed for the QD swivel. Tighten the mounting hardware according to the current manufacturer instructions and verify that the Quick Stop cannot rotate or slide.
