Looking at purchasing a used 6920 built in 2011…
Were 2011 rifles built with standard sized FCG pins? Will the lower have anything added to it to restrict the use of a auto sear? Did they come with an M16 BCG?
Thank you,

If built in 2011, expect to find standard pins. Yes, M16 BCG. Most, if not all, civilian Colt receivers will not accept an RDIAS.
Pretty good YouTube video here: https://www.youtube.com/watch?v=jdR7rEuLrvE
NVM…
Perhaps a clarification is in order…I have no interest in an auto sear, but I had seen some Colt receivers in the past that had a piece pinned into the receiver, which I prefer not to have…If the receiver is forged with a narrower portion to not allow a DIAS, that is fine for me…

I believe the Colt 6724 was the last to use the smaller FCG pins. All LE6920s (and more candidly, all Colts made after ~2009) have Milspec pins and lower receivers.
Thanks to all for the info…

Yea, def not milspec lower receivers.
The 2011 lower should not have a pinned sear block; rather, there is a sear block integral to the receiver present.
Yes or “sear web” as it is commonly called. The milling of the inside of the lower receiver (and lack of hole for sear pin) is anything but milspec. Selector stops are also milled off. NOT milsepec.
Lots of “milspec” nonsense here lately…
Disclaimer: I love Colt but hate misinformation.
Not concerned with “mil-spec” in this case…just reliability and compatibility with FCG parts I already have…
As stated earlier. You are GTG.
