well ive never had a bad experience with shipping stuff until now, I sent my bolt off to Mark at SAC and he mailed it back USPS. got an email saying it was delivered on march 8th with delivery confirmation, after fighting them for the past few days the mail lady finally admitted that she put it in the wrong box, cant remember what one she put it in, somebody got it and has not returned it! sucks cuz i just got my new hs precision stock, and swfa 5-20 and havent even got to use them yet!
