problem fixed, Silencer Central got it apart. the problem was a lack of information on the salesman's part. he showed me last Sept how to take to take it apart and line up the index marks but failed to tell me that at the bottom of the tube there there was also an index mark to fall into so I put it back together and the baffles did not index at the bottom and tilted and did not tighten all the way. good thing I only shot my 6mm and 204 or I might have had a baffle strike but everything looks good, now working on clean up. SC recommends clean every 100 rounds but have not heard about them not coming apart if going over 100 rounds, but this is new to me. thanks Jim
