| How do I get this off? Will a wrench work turning counter clockwise? |

I'm no AR build expert, but I feel I should say, you NEED to have the barrel clamped securely before torquing on the FH. 1st, FH are on a lot tighter than people think, especially with crush washers. Some of them take some serious torque. 2nd, the only thing keeping the barrel from turning inside your upper is the indexing pin, you don't want it to sheer off! If you are torquing on the FH while "holding" the rifle, you are putting all that torque directly on that indexing pin! (sit back and visualize it for a moment, and you'll see what I'm talking about... When you torque on the FH, you are torqueing the barrel, making it want to twist in the upper, and the only think prevening that is the upper) The key is to get the BARREL clamped (viced) down, then, the barrel isn't trying to turn in the upper, it's trying to turn in the vice... and that's fine. Do you have barrel clamps? Invest in some or make some! Gundraw Edit for sp. |

I've been trying to get it to move while holding the barrel or the front site post. I know better than to hold the upper or the complete rifle. The thing will still not budge, I need to by some armor tools I guess, I have been delaying it long enough. I even tried using CombatJack's tip to stick a screw driver through the slots , but that still didnt work. |

You may get by if you have access to something like a Black & Decker Workmate or similar type work bench. I have a cheap imitation and clamped the front sight base in the bench. I had to take the upper off the lower because the assembled rifle was too tall. This may give you the extra leverage advantage you need. But then my two rifles had a peel washer and the other had the old style split type lock washer. I've never messed with a crush washer. YMMV |

Yeah, you have guys clamping barrels by using wood blocks, or (for rebarreling) clamping receivers wrapped in towels into vices, because they are too cheap to buy the real tools needed. Then they ruin some very expensive parts. There was a guy in another thread who ruined a receiver like this. Now he has to buy an action block AND a new receiver to do the job right. Just go on and buy a real set of barrel vise jaws. They are quite cheap and will last forever. Heck, I'll loan you mine if you pay the shipping both ways and send me a deposit. |
