Remington 1100 410

[Donkey]

Hi whilst shooting a round of sporting with my Remington 1100 410 after firing a shot the end cap with part of the magazine tube came flying off

I was using factory Fiocchi shells 

has anyone an idea as to why this happened

i I have asked Remington but no reply so far

Metal fatigue at a guess.

Have you had the gun from new?

How long have you had the gun?

[Donkey]

Not new but from 2018 the gun has performed faultlessly 

[TIGHTCHOKE]

Not been bashed on the end cap of the magazine?

[Donkey]

No looked after with kid gloves

[TIGHTCHOKE]

Hopefully Remington or their importers will look favourably on your case.

Good luck

Overtightening of the end cap at some past time? That has then forced the threaded end away from the tube it is machined in to. The same effect as you might see trying to overtighten a stud into a blind hole in an engine block. The thing shears just below the place where the tightening force is being applied?

If the gun is s2 with a restricted magazine my remedy would be to cut off below the damaged portion and have a stepped hollow cylinder insert made, threaded at the end, to take the cap and then braze the thing in position.

Else if the original tube bears the "CROWN MR" mark you may possibly, perhaps, I don't know, need to re submitted to proof after any full unrestricted replacement tube has been crimped and then permanently fixed into the receiver?

Probably worth going on to remingtonowners.com Lots of information and some very helpful contributors. Do you know how old the gun is? 410 Remington 1100's and 870's are becoming quite valuable these days. I would agree with Enfield Spares about the repair option if an S2, as long as the bore of the repair part allows the magazine spring to pass through for cleaning. Of course, if an S2 you can never remove the follower past the crimp, so if applying heat to the tube, care must be taken if the follower is plastic. Good luck!

If you can get a replacement tube I'd perhaps proceed thus if the spring passage issue mentioned by IMPALA isn't fatal. That is leave your tube in situ and in pace on you gun and simply cut what is left of the "gone bad" end off. Take you replacement tube and cut off an keep its threaded section.

Now get a piece if thin tube the exact outside diameter of the inside diameter of your tube on the gun and the threaded end you've cut from your replacement tube. Make the length of that thin tube such that it abuts directly on to the magazine ring crimp. So the open end is in effect hidden from the spring by the crimp ring. This is the thing. Luck may be on your side with a metric thin tube working with an American imperial magazine tube.

You can braze the new threaded part to this thin tube and then on the full length part of the thin tube use a strong glue all along the outside surface of it and glue it into your existing tube. My theory being that if the spring will pass the crimped ring it will, logic dictates, also pass a thin tube of less inside diameter than the diameter of that crimped ring.

If that makes sense? Diagram shows the thing just before that final few millimetres of gap is closed up. Thus the integrity of the original magazine restriction is never in dispute.

Thanks enfield this is what has been proposed by a gun Smith I know

Looks like a neat fix
