Has anyone removed the flex adapter and put a magpul or oem stock on ? The flex system is cool but I want a magpul. I've done a little research and saw a few guys that did but wondering if anyone here did it. I heard the adapter is on with permanent lock tight type stuff. My main concern I guess is if the threads will be the same as a regular mossberg where putting new stock on will be simple and same bolt and thread size. Trading or selling the shotgun is not an option. My first Father's Day gift. So it's the only gun I have with sentimental value.
