Gunsmithing AR-10 dissassembly

[h4everything]

I am trying to get the barrel out of my AR-10. I put a wrench on the barrel nut to unscrew it and pull the bbl out of the upper and put it in the lathe to thread. Anyways I couldn't get it to budge. I quit when I broke a tooth on the wrench. Does Armalite solder or locktite the barrel nut on?

Thanks,
Jason

Try a little heat on the barrel nut. No solder, just loc-tite.

Heat does the trick for me.

Use a 4 foot bar on the tool that way you have better leverage. Always worked for me and you dont need to put loc tite on it when you reassemble. Use some moly grease on it and tighten to 30 to 80 pounds torque and line a hole up for the gas tube somewhere in that range of torque. You may need to tighten and loosen it multiple times before you get a slot to line up in that range.

Perhaps for removing a bolt action barrel this would be good advice. For a barrel nut on an AR, this is how stuff gets broken. If the loc-tite doesn't give with a 4 foot bar, what will? He's already broken his barrel nut tool without the additional leverage.

50ft/lbs is spec for Armalite AR-10 handguards, 65ft/lbs max for the BO stabilizer handguard. 80ft/lbs might get you some thread deformation.
