Then I read about how it's bad to send force down towards the stock. ended up drilling them dremelling smooth the tube. I did lose some finish though. I tried the socket method. worked horribly.

Use a bit about the size of the dent, and Follow up with a brake cylender hone. Works great I drilled mine. Use a bit about the size of the dent, and Follow up with a brake cylender hone.

It is exactly as you describe it on your site: http://www.rem870.com/2009/09/07/original-remington-870-2-round-magazine-extension/ The reason I was weary of installing such a product until today is because I could not find in my heart to to use a drill, dremel, or file on my gun to remove the dimples in the magazine. It gave me the impression of damaging my gun. Of course, hammering a socket inserted in the magazine tube to force out the dimples is out of the question – and should NOT be attempted. You will only damage your gun!! This site covers this topic very well here: http://www.rem870.com/2009/08/06/how-to-install-remington-870-magazine-extension-and-remove-dimples-...

Does a low impact precision file and a little time.. sound good too anyone especialy the gun? Then maybe a little blueing. No holes no pounding smooth? I have looked at both methods..

It takes very little effort to tap-in the correct size socket with a little oil on it--always leaving at least 1/2" extended so it can be gently removed. If you are lucky enough to have a 1/2" drive socket extension, you may find that works even better. When the socket is in place (and most of the dimples are thereby removed), GENTLY tap on the dimples with a SMALL hammer which results in a smooth surface, with no loss of metal and virtually no holes through the tube. As with Ken, I saw no damage to the finish. Start to finish time, 5-6 minutes. Grinding the dimples off or drilling them out is not necessary.

It works flawlessly. The dimples are in a steel tube. The best method for removing them is the same as any other metal working method (such as auto body work). There is no need to drill or file here. Simply work (GENTLY hammer) a lubricated hard object of similar diameter(such as pipe or socket) into the tube. Once in (it will be tight) simply use a metal working hammer (light weight) and GENTLY tap on the OUTSIDE of the tube (over dimples) until the "dimples" blend in with the rest of the tube. It's easy, and basic metal working. You will then have a smooth mag tube, void of any holes or thin weak spots that need rebluing ("socket method", done properly, will retain its finish).
