I just picked up my new M4; I cleaned, lubed and put it together. I sure like the look and feel but I have yet to fire it. The barrel assembly fits flush to the receiver; the forearms fit snuggly without any gaps and the magazine cap screws down tight. I can cycle the action and feed and eject the dummy 12 gauge shells without a problem. However there is a ¾” or so gap in the camo pattern on the magazine tube. Has anyone seen this before? Should I contact Benelli support about this or am I being too picky?
