I'm going to be building a SBR but got to thinking of how hard would it be for me to make it full auto? Could I do it and how much would it cost? Thanks guys

I think that you need a full auto lower and they are pretty pricy

RDIAS, Lightning Link, or register receiver. $8,000 - $18,000 and you are good to go

Become a FFL, then a manufacturer and pay the Feds $500 a year and you can make all you want.

As others have said the only way to legally make your current rifle full auto is with a Lightning Link or a Drop In Auto Sear. Expect to pay $7,000 - $8,000 for the Link and $16,000 - $18,000 for the DIAS.

It is my understanding that you cannot just drop a autosear in one just to make it auto. The manufactures left extra machine stock in the lower to prevent this and without the capability to machine the extra stock out you can't. I maybe wrong on this but I read it on the manufacuring web somewhere.

Depends on the particular receiver. Some, an LL or DIAS will indeed just drop in, others may require machining back to original Colt SP1 spec for such conversions to drop in.

Depends on the lower. My steel RDIAS dropped into my AX556 lower with the M16 FCG and bolt, and it has never failed since day one with no tuning at all or milling.

Yea it sucks. If it was before 1986, then a machine gun would be the same as any other NFA item. Basically $200 more. In 1986 though, they banned machine guns so only what was grandfathered in is left for sale. This means a very limited amount of stuff for MANY people that want them. I paid $17,000 for my sear. Well pretty much $100 for the sear, and $16,900 for the piece of paper making it legal. It's retarded, but it is what it is. If you can ever get one, I recommend it. They are supre fun, you'll be one of few that owns these things, and they are great investments if you ever need to sell them later on. Enjoy the AR!

You could do the next best thing and get a bump fire stock.
The DefendAR15 is around $500.00 and no stamp needed.

+1. Slidefire is 98% of the fun for 2% of the price. And yes I have used and owned or own both Nfa and Slidefire.

I have looked at those but heard mixed reviews.

ETA: How comfortable is the stock in general?

The AR 15 version of the bumpski AK stock is DefendAR15
and it is made out of CNC machined aluminum not plastic.
It is a high quality piece. My shooting buddy has the AK
version.

There is always the rubber band trick.
