I’m curious what spare parts MPX owners with a lot of rounds would recommend to keep on hand? I see ILWT has a kit together of spare parts for the MPX. Not sure I want to drop $165 on that and would prefer just stashing the most commonly replaced parts.

Anyone have access to a service manual/expected round count on when small parts need to be replaced?

I have a Gen 1 with 5k rounds, not that high of a round count. I bought one of the ILWT kits,  haven't used a part from it yet. Also have a Copperhead low round count no issues to date.

That's good to hear. I am only around 2k rounds on my K. Sounds like I'll just keep running it until stuff breaks, but was hoping to get an idea of what small parts to stash away for the future. Any competition shooters on here using an MPX?

IME, they are very hard on extractor springs.  However, you can use AR springs as spares.

The next would be extractors.  ILWT makes one.

I've heard that they can break aftermarket triggers.  My Larue MBT is still running strong, but I would not be surprised if it dies.
