I decided to change from a birdcage flash hider to a A2. The barrel is nitride treated and spins in my barrel blocks no matter how tight I get the vise. Before I buy a reaction rod type device do you guys think some free local pine sap from the nearest pine tree might get the job done?

I'd use a receiver block if the barrel block isn't working. You don't have to put too much torque on a muzzle device. Might be cheaper than the reaction rod

wrap the barrel in a rubber inner tube to give it some traction.

I owe you a beer!
Inner tube around the barrel and beating the vice closed with a hammer worked!

I knew that was an option but nitride pencil barrels for $125 don't pop up often and I didn't want to risk shearing the index pin on my hens tooth.

Not a problem. That's what I do with my home made blocks.

A piece of leather works also with or without the 2 x 4 v blocks

Another old gunsmith's trick, especially for custom blued barrels, is to wrap the barrel in solder and then tighten in a vise.

Powdered rosin also works.

which is pine sap...

That said, get a reaction rod or the equivalent Brownell's tool. It makes it easy to install or remove muzzle devices without having to worry about marring the barrel.

I bought a reaction rod and charged acquaintances a $5 one time use charge, or $10 for overnight use (remove install as many flash hiders/MB/Comps as you wish) and have already made my $100 back.  

Love my reaction rod!

I can't figure out a purpose for a reaction rod. -W

1. Holds the barrel for tightening/loosening the barrel nut and removing /installing a muzzle device.
2. Negates the need for clam shell upper vise blocks which transfer stress to the upper or barrel vise blocks
which can mar the barrel.
3. Works with all shape/style uppers which clam shells do not.
4. Use doesn't require removal of the hand guard which barrel blocks sometimes do.
5. Holds an upper assembly in the horizontal or vertical position while allowing it to be spun 360 degrees
for easy access to all parts.

We get a few sheared index pins a month from the reaction rod in this forum.

They are for installing/removing muzzle devices, not barrel nuts.

When installing a barrel nut, the upper should be clamped in a vise.
