Have a look at TAB gear rifle slips.I bought one in the summer and I think it`s great. Every sling I`ve had has either given up at the zip or the sling.This is not an issue with the Tab as you use the rifle sling and it has 4 heavy duty catches with no pressure on them The cover is made from cordura with a little padding round the mod and sight,it weighs ounces ,and for what it`s worth, I think it`s the dogs nads! Oh yes and you can get them made to measure.
