Definitely not common, but then again, most folks are probably using older M-A1s with the plastic guide rod. Another option for replacement would be to hit up btguiderods.com - he makes REALLY nice stuff.
This issue isn't a recoil rod problem, this is the striker rod. The only thing I can think of that could be producing that much abuse to this is a problem with the machining of the slide itself or the back slide cover being cocked to where it is putting pressure on the edge of the striker spring rod instead of it resting flat against the back cover. I wish you luck.
Take a nail, make sure it's straight, measure the diameter of the original striker rod guide end, and file or sand the nail head to fit. You can get the retaining ring in the other end the same way. Other than the spring load, there are no other forces on this part so the substitution should last the life of the weapon.
I've had problems with injection molded metal pieces from my Steyr, but also with a Smith & Wesson. Sintered parts don't like shock is the conclusion I drew. Most weapons manufacturers are moving to MIM since it produces either finished parts, or parts that are nearly finished with only minor second operations necessary. Owners should think of them as essentially ceramics, not from composition, but because they're sensitive to shock.
