I bought these in order to attach my new Savotta sling to my G36A1 service rifle. Unfortunately the slinghooks are actually not identical to the HK slinghooks. They are a little smaller. Therefore, on my rifle I can only attach them at the front ring but not on the stock in the back. This can be partially solved by adding a paracord loop, however, this in my opinion sarcrifices some of the stability the sling hooks are supposed to give. Additionally, when pushing in the sling hook, the moving part sometimes flexes and therefore does not want to the rest of the hook. One therefore has to pay extra attention while pressing. In conclusion, not what I expected from a Savotta product that's supposed to be like an HK product.
