STG-556 REPAIR NOTICE and DETAILS

   If you have a black Limited Edition STG-556 with serial numbers in the range of 600-BLK00104 to 600-BLK00259, please send it back to us even if you are not experiencing any operating issues at this time. There are some upgrades that we need to perform, and we will go ahead and make the necessary changes. Any STG-556s with serial numbers newer than this range including any green or tan Limited Edition and all production guns will already have the upgrades and will not need to be returned. These upgrades are merely a reliability issue, not a safety issue. Also, if you were as yet unaware, we have experienced a functioning issue with some of our trunnions that is causing some intermittent feeding problems. We have the problem rectified and we are installing new trunnions now. Please return your complete STG-556 minus the Pelican case and accessories with your return shipping infomation and we will repair it immediately and ship it right back to you. If you have taken possesion of your STG-556 from your dealer, you can ship it directly to us without involving your dealer, and we can ship it directly back to you. Thank you for your patience and understanding for any inconvenience during this brief repair and inspection period. If you need our UPS shipper number, please call 814-363-9260, Ext. 10 (Denise Thrush) or Ext. 21 (Keith Adkins). Also, please feel free to call Tony Marfione on his cell phone at 814-558-5333 if you have any specific technical questions about any of these upgrades. Below, please see the detailed photos with an explanation of what repairs and or modifications we are performing to get your STG-556 back in perfect working order. We are also cleaning, lubricating, and doing a full routine maintenance check and inspection on your firearm while we have it, compliments of MSAR. Please check back here in the next few days for new range video and pictures, and also for any updates we may have for you. Please do not attempt to modify your STG-556 yourself as this will void the warranty.

Thank you, The MSAR Team
