I need to remove the lower receiver extension nut on my BCM lower.  It is currently staked.  I am adding a sling mount.  How do I re-stake the nut?  Is there a special tool i need to pick up off Brownell's or am I better off sending to a gunsmith?

Hammer and a center punch.

Just gently fold a little of the metal back into the notch.

A punch or small screw driver will work.

As simple as that, huh?  I assumed there would be a $40 tool involved (not counting me).

I could sell you my small screwdriver for $40, but you'd be better off just using your tools.
If you have a hammer and a punch/screwdriver you can do it.
All it needs is a little material from the endplate back into the notch to prevent it from unscrewing over time as the rifle is fired.

If its something you don't want to do yourself then taking it to a gunsmith might be better.

I used a concrete nail because it was closer than the punch.

Don't let this stop you from buying some tools though

You need, two men, a truck, a dog, a baby elephant, two D9 Caterpillars and a sheep. That's just to remove it. I removed one of mine and I'll never do it again. I then bought a new nut and end plate to put on there when I re-assemble it.

Seriously, it was a major pain to get off.

A lower vise block and something a little longer than the typical 7 dollar cheap wrench will get any staked nut off with ease.

I stake all my own..I prefer to use an automatic center punch, it seems to yield great looking results.

This +1
You will not even need to use a hammer. Just press the punch till it "pops", do this several times. It will move just enough metal so that the castle nut will not move without a wrench and a LOT of torque. The finished product will look professional and last as long as needed. Is a simple process.
