Has anyone any experience of removing the barrel of an S410 and the Gas chamber ?

I have recieved some metal finish sprays from brownells in america and wanted to finish the barrel and gas chamber in stainless steel.

Obviously I'll empty the chamber completely but is it all easy to take apart following the exploded diagram or am I going to hash it up in a big way ??

I can work with tools without supervision and/or cutting myself <img src="http://jsramsbottom.co.uk/bbs/e/icon_wink.gif" alt="Wink" width="15" height="15"><!--graemlin:--> <img src="http://jsramsbottom.co.uk/bbs/e/icon_biggrin.gif" alt="Big Grin" width="15" height="15"><!--graemlin:-->
