Any HK guru's on here??? I've got a PTR 91 with a small problem, I've posted on the HK web sites and a couple of others and got some suggestions but what I really need is someone that knows what they are doing to take a look at it. It fires fine, problem is when the bolt rides forward on an empty chamber you cant open it with the charging handle, it has to me mortared to get it to open back up. I'm tempted to order a new charging handle for it as it seems like that one on it just isn't giving enough leverage when the handle is pulled open. If you know anyone who is good with HK rifles let me know, preferably in the OKC or Lawton area. Thanks
