M16 cut, (m4 cut, full auto pocket), is a cut in the lower reciever where the fire control group goes. The reciever is cut thinner all the way back to the rear takedown pin, along with the shelf taken back to the rear takedown pin.
This cut allows a select fire, fire control group to fit into the lower reciever and allows an auto sear to fit into it as well. The auto sear cannot be installed without drilling the third hole, which is illegal unless you have the proper licenses.

AR-15 Cut means that the reciever is not m16 cut. The shelf is extended further forward and the walls are thicker all the way to the selector switch/safety hole. This prevents a full auto fire control group with the auto sear being installed. In order to do so, you would have to mill out the lower, and then drill the third hole. (Just drilling the third hole is what's illegal.)

AR-15 cut lowers can come in a "low-shelf" or "high-shelf" configuration. A "high-shelf" prevents a registered "drop-in auto sear" from being installed. A "low-shelf" allows a DIAS to be installed.

An auto sear and a drop-in auto sear (DIAS) are different. A standard auto sear works in conjunction with a select fire fire control group and would make the gun just like a M4/M16. A DIAS allows you to shoot your AR-15 full-auto but does not allow you to switch between semi auto and full. You can buy a registered DIAS legally. You can also buy machine guns legally. They both are just expensive and take time to get approval.

Zrtactical.com makes a full ambi lower

 

[Robert Richardson]

Lots of information that I can do without but, thanks, I guess.

 

[Robert Richardson]

You didn't have to read through it. Lol

I didn't

 

[Robert Richardson]

Yes sir. I did say "thanks". Maybe I'll get sarcastic next time.

It aint worth it. lol

UnBrandedAR makes a stripped lower with a right side bolt release that works with a standard bolt release. They include the ambi bolt release parts with the stripped lower. The paddle could stand to be a little more robust, but other than that, it works as advertised. I do question how mush abuse it will take before it snaps off. I bought my lower when they were on labor day sale awhile back.

Mr Stoner weeps, if he wanted it to be ambidextrous, he would have designed it that way.

Saint Stoner (Peace Be Upon Him) was a genius, but people will always find ways to "improve" existing designs. The AR as designed is awesome, but I cannot keep myself from tinkering on it. What is it, something like 60 years of continuous service in the our Military and they are still upgrading it? Even the new Sig 6.8 rifle is based on the design. It only rivals the AK and maybe the FAL & G3 in terms of active service.
