| 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? |

Quoted:
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 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. |

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

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

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. |
