I have a M2 Field 20 ga. and both rear and forward stock are sticky. I just pulled it out to take a look at it today. How disappointing. I was ready to buy a slug barrel and a slug forearm for it. Going to hold off till Benelli responds to my inquiry about this problem. . I paid a lot of money for this shotgun and hope I’m not disappointed. I can’t even use this shotgun in this condition.
