I mean, it's a spring and a guide rod.
2 different pieces. I don't think they were ever attached, except by friction.
They were attached. It's a captured recoil spring sold as a unit. Glock and other gun makers do it this way, too.
But as you note in another response,
the darned thing will still work (or can be made to work with a minor adjustment) even though one end has come loose. If it's cheaper, I suspect that a Glock recoil assembly could be made to work, with minor tweaking, as the FNS and Glock recoil assembly assemblies are almost identical in design and size (for comparable slide sizes.) It may even be possible to reattach the disconnected end unit with the right type of glue...
I agree with Groundhog34 that the guide rod should have been replaced under warranty after failing in less than 400 rounds,
but, his very widespread outrage and implicit claim to the contrary, it's not the end of the world. Rather than being able to say "it was a defective part, replaced under warranty", Groundhog34 is now free to rant about FN America's crappy warranty coverage. Had a mag spring failed (gone soft, or twisted) after relatively few rounds, FN America might have replaced that spring (or swapped mags with him), and it might have been more costly for them. As I noted in my reply to Groundhog34 on another forum, I think FN America should have replaced a part that failed after such limited use. It didn't and FN America probably shot itself in the foot by not doing so.
FNH makes great guns. I have three FNS models -- nice guns. The parent company, FN-Herstal (FNH) owns Browning and Winchester, and was the original manufacturer of the Browning/FN Hi-Power handguns. FNH still makes a variety of high quality rifles and shotguns.
The U.S. military has used FNH weapons for decades and currently uses The MK17 SCAR, The M249 SAW, the M4A1, M16A4, M240B, M2HB (a tripod-mounted machine gunn) and has contracted to provide with several other FNH variant models under. The FNH military weapons are widely used by most of the NATO militaries and by militaries elsewhere in the world.
FN America's warranty covers the gun, whether bought new or used, and not many gun makers do that. Some gun makers will send small parts, free of charge, but won't do major warranty work if the gun was bought used. For really big or expensive issues, any subsequent FN gun owner's gun is still covered by the warranty, and I've read of owners them getting their FN weapons serviced/repaired under warranty without problems. I've heard nothing about guide rod assembly (GRA) being replaced
or GRA failures, until Groundhog34's problem raised its ugly head.)
The FN America manufacturing operation in South Carolina was set up to allow FNH to continue selling weapons to the U.S. Military. It's a relatively new operation and I suspect they're still operating on a shoe-string. Civilian weapons have not been FNH's primary marketing focus here in the U.S., and that may explain why things are the way they are. I suspect it will get better.
