figgy Posted August 4, 2014 Report Share Posted August 4, 2014 As title I noticed when cleaning my semi auto a Winchester SX3 when I got the carbon off the magazine tube where the gas valve sits the surface metal looks like it's melted only the thickness of tin foil so it won't affect performance of the steel but it might wear the o ring out a bit quicker. The tube is thicker at this section, anyone else noticed this with theirs. Not sure if this has been asked in the past. Only get the semi out for fowling season then back to bed for rest of year.

Cannon Posted August 4, 2014 Report Share Posted August 4, 2014 I've never had an issue with my SX3 with regards melting mag tubes, or anything else for that matter. Sometimes it's difficult to clean this part of the mag tube, but it always comes up perfect after some elbow grease. Quote Link to comment Share on other sites More sharing options...
figgy Posted August 4, 2014 Author Report Share Posted August 4, 2014 Think I noticed this before putting it away beginning of the year, off shooting big loads. Lots of hot gasses hitting this part of the tube. Figgy Quote Link to comment Share on other sites More sharing options...

Lots of hot gasses hitting this part of the tube. Figgy I would have thought that it would have to be ever so ever so hot and very constant to melt the mag tube . Sure it's not corrosion ?

Figgy I am not familiar with the particular firearm in question, but it sounds as if you have it sussed yourself as possibly a type of flame cutting erosion caused by the hot gasses similar to that seen on the top-strap on some revolvers suffering the same issue?

kent Posted August 8, 2014 Report Share Posted August 8, 2014 Cant see it melting from gasses it chromed, left un-cleaned it will cerainly corrode though. Have to take your word for it melting it just sounds so unusual Quote Link to comment Share on other sites More sharing options...

Have to take your word for it melting it just sounds so unusualMy MP153 was like this when I bought it - the mag tube looked like it had never seen a cleaning kit, the corrosion had gone through the (very thick) chrome, and the corrosion was eating into the tube, to the point where the gas seal was getting damaged. The owner had screwed the adjustment way in to compensate for the pressure loss.New mag tube and seal put on, although to be fair you couldn't tell anything was amiss as it still cycled anything you out through it. Ok, so I'm fussy... Yes, lack of cleaning and corrosion is a more likely culprit than "melting the tube". The gases aren't *that* hot.

figgy Posted August 9, 2014 Author Report Share Posted August 9, 2014 The gun gets cleaned, it's not corrosion. I'll take a pic tomorrow and post it up. It's only the very top surface layer of the metal that's affected. Anyone who has taken a blow torch to metal will have seen this on the metal as you heat it before pressing the oxy to cut. The gun is under warranty so if it starts to affects operation it will be back to dealers at end of season for repair. Might just be me being pernickety, but not by some standards on here.

strangford wildfowler Posted August 10, 2014 Report Share Posted August 10, 2014 My baikel is gas operated and where the gas hits the magazine type there is a wee bit of pitting on it and this happens to most gas operated shotguns is just because the gas is always getting at it when being used no matter how well it's cleaned it will happen Quote Link to comment Share on other sites More sharing options...
