I do not own a 1014 but I believe they are marked a certain way though it escapes me at the moment. Your foregrip is certainly new, those have only been out a couple of years. Here is an old thread about using the serial number to date the gun: Please do keep us informed what you find. We are a friendly group and most everyone is happy to help new members. Welcome to the forum!

Honestly, those problems sound minor and well within normal variation. I imagine the stickyness is due to manufacturing oils not being throughly cleaned before shipment and will vanish with its first cleaning. The variation in color of parts is also within normal parameters. Not long ago some M4's were shipped with a bluish sheen. Though I never saw one in the wild; I consider those very desireable though some were less than happy. Function is paramount and I expect none of those "faults" will impact operation at all. The M4 is, IMO, The King of Shotguns. I am sure you will love it as 99% of us do, congratulations on your purchase!

It's the size of the shell used, not all shot shells are the same length from different manufacturers; there are a few threads on this subject.

It might break but I doubt it unless it's really smacked hard at which point, the light mount breaking would probably be the least of my worries.

That's some smoky shells you're firing there! My point was, if placing a light on your gun putting the light underneath will eliminate barrel shadow. Again, if you know where your target is that's not a problem but if you're clearing a room for example, you may not always know where a threat lies. Placing the light underneath gives you better 180° visibility left and right. Like this, here's one of my M4's:

You certainly will to the right with the configuration shown. It's fine if you know your target, not so good if you're searching for a target.

Placing the light underneath the mag tube will eliminate the inevitable barrel shadow you're going to get with a side mount.

There's a youtube video showing shotshells deforming in a box magazine over time, the 590M IIRC. A good rule of thumb is to inspect loaded shells every 6 months or so and replace deformed ones.

I have rapid fired my M4 before just for the experience and to see if I could outrun it (I couldn't); pretty fun but not something I'm going to do everyday. I've also pulled both triggers at once on my Baikal SxS coach gun, there's no padding on a Baikal, not doing that again either.

Everyone please keep posts civil and refrain from personal attacks, thanks.

It is sold, sorry.

Welcome to the group! That's a fine looking M4 that will give you many years of reliable service, congrats!

A wave washer is probably the best option IMO. Any rough idea on cost or timeline till release? Really looks sharp!

That's not OEM, I've always heard it called a "bolt release tab". https://rxarms.com/products/benelli-m4-parts-and-accessories/benelli-m4-bolt-release-tab/
