Wouldn't it be easier to the remove the tube cap and retaining ring then pull the spring and follower then to remove the whole tube?

I don't have the manual in front of me but IIRC the cap removal was a revision on models made after mine. |

Quote HistoryNot for my model it is different. The cap is solid, not split if it were I would already have swapped out the factory follower. That's a hack way to remove that cap, should be done with a pair of snap ring pliers. LOL. |

They were very helpful to me when I wanted to know more about the shotgun I received as a xmas present. IF you call, make sure you have the s/n or shotgun in front of you. |

I will post some pictures soon. I have already spoken with Benelli. According to the person who I spoke with they do not have records going back that far. I found that hard to believe, but they said for the early H&K imported Benellis that is the case. I asked about how to remove the tube and the person was not willing or able to give advice. The tube has to come off. I have spoken with a colleague and they had a gunsmith perform the procedure many years ago. I inquired with him if he know how and he does not know. I'd bet it will involve getting some hear into the tube to release whatever thread locker was used. I'll get some pics posted latter. ETA: Pic added.

I find it interesting that yours is an early HK import. I know this sounds odd but, call HK and ask them. I know of a FFL that a while ago had a dozen M1S90's on order directly from HK that were HK imports. He was waiting for HK to finish refurbishing them. |

OP lets see the rest of the mag tube. Especially where the mag tube goes under the forearm. What I'm seeing here looks to be a factory mag tube extension. I'm betting yours has a knurled knob just ahead of the handguard. Remove the barrel clamp first. Then pad the jaws of some channel locks or vise grips with a good piece of leather And it should come off.
BTW: How many malfunctions has the factory follower caused?  Benelli M3 disassembly |

Doesn't the M3 basically just have a tube extension? The one's I've seen look like you could just take the barrel clamp off and unscrew from the main tube. I would need more pictures to be more help though.
There's got to be a way to get the follower out. |

I have an M2, not an M3. Here is how I removed the magazine tube. I stuck it in a barrel vise and cranked it down so it wouldn't slip, but not so tight it wouldn't crush it. I then used a heat gun for a few minutes until I could move the receiver with a rubber padded C clamp. Eventually it broke lose with a little heat. Hopefully you don't habe to do something like that.

A heat gun and strap wrench. Its what I did on my HK import m3 years ago. Heat it up a bit, try to turn it, it shouldn't take a bunch of force, if it does apply more heat, and keep repeating until its comes off. I had a hell of a time cleaning all the thread locking compound out of it before re assembly.
I wish I hadn't sold that to a buddy. |

You don't, the magazine tube must be threaded from the receiver. I read an article that state there were 189 units of my model that came into the states configured this way. |

Zero issues with the follower, but I customize everything because I like to and America fuck yeah!

Here is the schematic. As you can see the factory magazine tube is threaded into the receiver.
ETA: I think it is going to be a heat gun and slowly heat until whatever thread lock they used lets go. I am going to want to remove the forend slide support (part # 59 below) as it is plastic and I'd bet it could melt. Any idea what type of thread lock Benelli uses?  |

I'd say a good basic heat gun will do what you need here. They should use a lower temp threadlocker in anticipation of having to service the mag tube spring. Put the receiver in a padded vise and heat where the tube screws in until you can spin it out. |

I'll also use a low strength thread lock, no need for high strength there. Just got to make sue there is no plastic around that area before heating it. |
