I am very familiar with the AR from 10 years military service (LOOOOOONG ago) but my new acquisition has something on it I do not know about.
Here is a picture

What the heck is that one thing on the receiver that looks like a control but is not? (The 'bar' above the trigger) it looks the same on both sides of the receiver like it is an ambidextrous control but it does not move at all.

Haz..
That like something similar to the KNS anti-walk trigger pins. Hard to tell from this distance, but they do not look like KNS version though. Either way, those are covering/holding where your trigger pins are located.

I was told that there had been trigger work on it but he didn't know what had been done exactly.

Hey, nice rifle.
No big toe? ;D
you had to know that was coming.

When I said "it's in the other pix" I meant 'picture' not 'pitcher'. ;D

Bidah is on the right track, lt covers both hammer and trigger pins, so most likely, a pin retension device, although I do not recognize it.

I think it may be a toe grip, Haz.

Haz,
Those are KNS anti-rotation pins. They keep the hammer and trigger pins from drifting out of the receiver as well as keeping the pins from rotating within the receiver holes.
You see them more on full-auto setups so the steel pins don't rotate and enlarge the holes in the aluminum receivers, ruining what is a very expensive investment.
How effective they are is open to debate, but it's cheap insurance against ruining a CIII transferable FA receiver.

Thanks USSA-1,
Mine is NOT FA but I was told it had 'trigger work' done to it.

Bidah was right when he said it didn't look like the KNS non-rotating pins, and USSA-1 was right when he said they are KNS. It's the NEW GENERATION 2 PIN SETS that don't look like the KNS design many of us have seen before. None of the thousands of M16s I inspected and worked on in the army had loose pin holes in the receiver so I doubt non-rotating pins are actually needed.
