Question. I just swapped my standard  safety for a ambi safety and  I noticed that it will flip to the auto select mode. Is this a problem?  

Lucky dog

Hear that? That's the sound of the swat team assembling on your lawn.

 

IANAL, but does it do the bad thing in that position? If it is still only semi-auto function (and the part was not market as part of a full auto kit), I'd assume you are fine. 

 

ETA:

 

This seems like they figured it out:

Post 13 is interesting.

yeah if it does not shoot in full auto your good to go

 I removed it.  It says semi on the bag it came in.   Thanks all.

I always use the BAD ambi-selector. They come with different levers and can be setup the way you like it. They are a bit expensive but as a lefty I always use them and for the mag release I use Troy.

the tac con 3mr comes with the selector switch capable of going to the third position.....supposedly 50 state lega.

Looks like I'm going to try a bad ambi selector.

You won't be disappointed. Worth the money in my opinion.

Ditto on the BADASS.......

As a southpaw, I have installed the DPMS ambi safety http://www.midwayusa.com/product/217314/ and the Norgon ambi mag release http://www.midwayusa.com/product/918403/ on all my AR platforms, including the AR pistols.  The selector NEVER goes to the third position.

 

And thank you, Gene Stoner, for putting the bolt release on the proper side of the gun!

I note for the discussion that there is a vendor selling a drop-in bump-fire (excuse me, "positive reset") trigger with accompanying "evil 3rd position" safety that claims ATF approval:

Holy shit i'd drop the $400 no questions asked. Well except maybe one question to the state of NJ.....

I took a carbine 3 class at GFH a few months back in PA and one of the instructors lent me his carbine with a tac con trigger for the final exercise. I suck at bump firing but it was very easy to fire 2-3 rounds at a time in a controlled manner. It was pretty cool, the only downside is that I had to transition to pistol before anyone else.

dumb question......that 3rd position isn't illegal or considered an evil feature in any way, is it?

No, Tac Con even includes a letter from the ATF declaring it to be legal. It just creates an incredibly light trigger pull and extremely short trigger reset. Its very controllable and a lot of fun though I would probably recommend against installing it on your defensive carbine that you keep next to your bed at night because it has such a light trigger pull.

BAD ASS all the way.  I use them quite a bit.  There's an eBay seller who has them for a good price and free shipping.
