Runaway Mac!!! Help Please!

[Ziess21]

I just got my M11 this weekend and the first time out it became a runaway

I think it is the sear, but it is only slightly rounded.

Where can I get the best replacement sear that will work with my Max-11 that will be here Monday?

Did you look closely at the sear notch in the bolt? Is it peened down? You could hit your sear with a file.

 

[Ziess21]

Bolt notch is nice and square. Would I just need to file the sear to be square again?

Weren't using Remington 9mm in the newer green-white box or the yellow box was you ?

 

[Ziess21]

I was for some but tried several types with the same results. What's the deal with that ammo anyway?

underpowered ammo causes runaways
