Psa-never Ever Ever Do This!

[BPTactical]

A customer brings me an AR built by a local shop to do a little front end work. I grab the trusty barrel wrench and apply some pressure to the barrel nut. Won't budge a bit. Put some more OOMPH to the wrench and it still won't budge. I grab the 1/2" torque wrench so I can get some more leverage and it stiil wont budge! WTF? I double check to make sure there is no mechanical reason it won't turn and I see none. This time I grab the 2.5' "cheater" and put the toque to it-it slowly starts to turn but still has an ass load of resistance. After a few minutes of sweating and cussing it finally comes off and I can pull the barrel.
Wanna know why it was a Biatch to get off?:




NEVER EVER EVER use Loctite on a barrel nut!
They should only be lubed with a moly based grease or anti-seize.
Don't use anything with graphite in it-it can cause a corrosion issue due to dissimilar metals.
40 ft/lbs of torque, and if needed to align the next notch for the gas tube some additional tightening, not to exceed 80 ft/lbs.
Never back off the nut to line up the gas tube notches-if you feel you have to tighten it too much then try another barrel nut.

Using Loctite on a barrel nut is just stupid. If torqued properly it is not going to loosen, and even if it did it is not going to back off, the gas tube will prevent that.
The only time Loctite is acceptable in barrel mounting is on a match rifle, and even then I would hesitate-some builders will Loctite the barrel extenstion to the reciever, knowing that the pair will never be disassembled.

Damn lucky the nose of the reciever didn't snap off!

Just an FYI.............

LOL you need to slap that person loctite, superglue, duck tape all in the same family.

Let us know who so we never ever go to that fool.

Same thing was on mine, but not that bad.

Quit your complaining. Little red loctite and a few Ft lbs. Just wait till ya see a Fal barrel that has red on it and has been tq'd to 160 lbs.

6' of bar on the receiver wrench and two guys pulling on it. It only broke loose after some heat.

[gnihcraes]

Almost looks like there is thread tape on there too?

Lucky it didn't destroy the front ring of the receiver.

I want to know what sort of perversion of mind translates "anti-seize" into "thread locker"

Glad you managed to get it loose. Lucky for the customer to.

I was gonna say, fire is about the only way to crack the red oped.
