Replacing the Sig Sauer MPX Trigger - Should you "Upgrade?"
Steve shows how easy it is to replace the trigger in a Sig MPX (including a trick to make it easier without removing the safety lever) and talks about why you might want to, but warns about warranty issues that might make you think twice.
I’ve moved many of the firearms-related posts from my personal site over here to RGR, but I’m leaving this one over on SteveJenkins.com because Bill Geissele (of Geissele Automatics) left a comment over there, and I want it to be preserved.
So after you watch this video, go check out the original blog post at http://www.stevejenkins.com/blog/2015/06/will-upgrading-the-sig-sauer-mpx-to-an-ar-15-trigger-void-your-warranty/.
