Does the MCX have any charging handle issues similar to the MPX?

Any reports of the mPx handles actually breaking? I just thought they were scarring up the uppers since there was play in the handle.

How did they break?  What is their inherent weakness?

I can't speak for him but I had to replace the roll pins in the charging handle twice and the handle itself once in 500 rounds. The handle would fail to unlatch the opposing latch after a short time.  It appeared to be a design issue and Sig did not take to heart the lessons regarding the ar15 charging handle.   I sold the rifle and may buy another if and when Sig figures it out.

Exactly this. Poor design. I'm glad I have a non ambi CH for my MPX.

Are there any remedies for this problem?

Lets hope the MPX handles hold up better, especially since they are proprietary. No issues out of mine so far, other than it being a little sloppy in the receiver.
