Calling all Benelli experts: M2 Tactical 5 shot mag extension tube problem...

[Balrog]

I just got a M2 Tactical with the factory 5 shot mag extension tube. I took it to the range today before breaking it down, and was able to load 5 rounds easily into the magazine. When I got it home, I broke it down for cleaning and reassembled it. I am now able to only get 4 Winchester shells in the tube. I can put 5 Remingtons in, but it takes a push on the fifth to get it to seat. I used my caliper, and know that the Remingtons are just a hair shorter than the Winchesters.

Problem is, I was able to get 5 winchesters in with no difficulty before I took it apart.

So now I am looking trying to figure out what the problem is. There is a two piece cap at the end of the magazine extension tube. One peice is a donut with a flange in the metal at the inside of the donut hole. The other part is a cup shaped piece of metal. The flanged side of the donut fits into the cup, and then this is dropped into the mag tube. The donut piece was postioned at the end of the magazine tube, you could see it when you looked at the end of the tube. That is how it came from the factory, and how I have it reassembled. Is that correct?

I was playing around, and if I leave the donut off completely, and turn the cup so the inside is facing the inside of the mag tube, I can fit 5 rounds of any shells into the tube without difficulty. Is there a problem with just leaving out the donut completely, and using it that way?



Thanks

I was just looking at the Benelli website, and there is a photo of an M2 from an end on view, and the gun in the photo does not seem to have the donut piece on the end of the magazine tube, as mine was. It appears the cup I was talking about is at the end of the tube, and oriented so that the inside of the cup is inside the magazine tube.

Does anyone have a photo of the end of their magazine tube? I think mine may have been put together wrong by the gun store.

Ok, as I continue talking to myself, I think the thing I am calling the donut is the retaining ring for the limiter. I do not think it is supposed to be installed when the limiter is not in the gun.

Hopefully someone will come along to confirm.
