I ordered and just received a mirage strap for my TRG-22. It's an elastic band with two rings (one at each end) that are supposed to hook onto something on the rifle to place this strap above the barrel. The problem is, I can't find anything on the rifle to hook them on. Luckily, I installed a muzzle break that has a fixing screw on top, so I can hook the front ring to this screw. At the rear, by the action, there is absolutely nothing. Anybody knows how is this thing supposed to work? The outfit who sold me the strap claims that it is for Sako TRG. Did they forget to enclose some hardware or is there something on the rifle that I can hook the strap on?
