Unless I covered or filled those M lock slots with something I'd end up with ice, snow, seeds and spruce/hemlock needles getting in there between the mag tube and forend. If they were going to do a removable mag tube, I'd have preferred an inner/outer tube arrangement like Henry. You can see in the video that the trigger has a lot of creep in the final stage and it's going to need work if a crisp break is important to you.
