Hello,
I purchased my Benelli M4 shotgun on December 21, 2015, and have fired approximately 400 rounds through it. While cleaning it today, I noticed what appears to be a hairline crack. I would appreciate your guidance on whether this is a cause for concern.
I have attached photos for reference, including one with a red arrow indicating what I believe to be a hairline crack. Additionally, I have included an exterior view of the shotgun with a reference point showing where the crack is located internally.
Please let me know your opinion.
Thanks-
