I have one of the older airgun gear rigs that you are inquiring about. It has been used by me only. If you want to swap out yours for mine we can.
Mine has the older more flexable straps on it (they are more prone to twisting ). That is the reason I wanted to get the newer one but have this one. I don't know if you are that interested in getting the older one that much. As stated mine have some straps that over time can and in my case do twist but other than that it is ok no damage to it.
Give me a shout if you are interested.
