QD Swivel, HK Small Pin (MP5k rear)

Ambidextrous QD Swivel — engineered for adaptability. I designed this rear takedown pin and QD swivel for the rear lower pin that goes through the trigger housing on the MP5k. It replaces the factory pin and gives you a secure QD sling mount on either side of the firearm.

• Reliable retention: The E‑clip locks the pin in place. I tested it through three MP5 training classes and 18 months of use, and it never failed. To make disassembly easier and account for the manufacturing differences in stocks, I include two heavy‑duty and two medium‑duty E‑clips.
• Practical engineering: I avoided a threaded‑nut designs that can loosen and cause your firearm to fall. The E‑clip system keeps the pin secure without adding complexity. While I haven’t run formal FEA, the design handles real‑world demands. (Please skip the Die Hard HVAC hang – but if you want to see just how strong my design is it will support a 200lb load if you use a quality sling mount https://www.youtube.com/watch?v=GJikLxR2xvU&t=11s)
• Made in the USA: A local CNC machine shop produces this for me. So when you buy this you are helping to support me and my wife and 4 families at the CNC shop.
• Made of steel, you can easily adjust the fit with a file or grinding stone if needed.

This swivel gives shooters a dependable, adaptable sling solution. It combines straightforward design with proven durability, so you can trust it in training, at the range, or in everyday use
