I wrote ISSC an email describing some of the issues that have affected MK 22 owners on this and other sites. I stated that I would post any reply as a way to get the ISSC party line on these concerns out to the user base. So here is the reply:
Dear Mr Hinze, Thank you for taking the time to write us. Every suggestions to improve our products are very welcome and we take them all very serious. Some of the mentioned issues were already solved. For example, we use a stronger material for the stock now, so the stock won't brake anymore. For the three upper rails we use threaded bushings and thread locker (thread locker in general on every screw) to make sure they won't come loose. You are right there is a learning curve with every product you place at the market and we will never stop to improve our products and you are right again this is only possible through a good communication with the users and people like you giving use some useful feedback. Regarding your warranty, usually modifications like you did on your weapon would harm the warranty but because of your special situation through the change of our importer it won't void it. Thank you again for all you suggestions and be sure we take a close look on every of them.
