The R3/3 Sling System for the MP5 was introduced in 1973. The sling itself employs three attachment points. The front point is the eyebolt. The rear mounting point is on the buttstock (MP5A4) or butt (MP5A5).
The third attachment point was a mystery to many when they first encountered the MP5. It is a metal 'U'-shaped clip fastened to the left side of the magazine well. Some thought its purpose was for hanging the MP5 on a hook on a wall, while others couldn't explain it at all!
