No......this will not make your ar full auto. That function takes place in the lower receiver. This is an upgraded BCG. A full auto ar will be better served with this because of the stress placed on the BCG with full auto firing.

no its just a Bolt thats designed for full auto use. i think.

It will in no way make your gun full auto and is entirely legal to use in your AR15. It has been discussed to no end on these boards. The only difference between an M-16 and AR-15 carrier is the M-16 carrier has more material on the bottom rear to trip an auto sear. Some will tell you the additional mass may increase reliability, but that may be entirely theoretical. Just buy it and don't worry about it. I have one of those and it is a very nice BCG.

Well if its designed to handle Full Auto stress then i def. want to get it....

Many people use ar15 (semi) carriers and have no problem if you want it thats cool - but its not necesarry(sp?).

I sold my BCM carrier when I parted out an upper for new build funds. Seeing as the ATF has a habit of changing things to screw people I feel it best to use only semi auto parts from now on. Just personal preference.

I dont think you quite get it yet. Maybe a little research might help some.

If used in conjunction with a properly machined lower and a full auto fire control group, the M16 bolt carrier group will allow for full auto fire.
Basically an M16 BCG will not give you full auto, but you cannot* get full auto without it.

*I know there are exceptions.

Not exactly.
It is designed to facilitate FA when used with the rest of the FA parts.

It would be more accurate to say that it's meant to ALLOW full auto fire, when the rest of the rifle is of a select fire configuration. Semi auto carriers with the cutaways that prevent thei use for full auto are just as strong. They just won't work in a selsct fire piece.

There is a much stronger case (IMHO) for the shrouded firing pin carriers, regardless of how the rear of the carrier is machined.
The shrouded firing pin prevents the hammer from fouling the pin, sometimes bending FPRPs or other mischief.
