I've got a MCX coming and I'd like to run the MCX upper on my M16. Has anyone had any luck getting an autosear trip from SIG?

It depends on the upper/carrier you got. Sort answer is yes some will, but I think Sig is also shipping ones that have a carrier that won't trip a sear.
You'll see shortly I guess when it comes.
Personally I don't like the fat handguard of the MCX, or the folding stock, so I haven't played around with a lot of them.
I Just stick to BCM or PWS.

This is the part I'm talking about, looks like its held in with 2 roll pins.
