Only one thing about that link, you are not in violation of the law by having the M16 carrier in your AR15. I’m surprised they never edited that.

Outstanding, thanks guys. How are you not in violation does the law only concern the fire control group?

I don’t know if this shows enough but this is a BCM brand auto carrier.I had it chrome nitrided.

this at least shows how close the underside of the carrier comes to the forward assist notches

here shows where the pin is shrouded.

I need to get the other end showing where it is extended more than a semi.
