Posted 25 December 2013 - 08:26 AM

So I've been trying to get it off all morning and it won't budge.  I've been using an armorer's wrench of course.  Is there thread lock on it or something?  Do I need to heat it?  Anything to worry about with the barrel/hop-up in there?

What is the best way to situate the receiver?  I'm afraid to put it in a vice, because I feel like I might crack or bend the receiver if I pull/hit the wrench the wrong way.

I suppose if worst comes to worst... I can cut the delta ring/spring assembly and all that stuff right off and force the nut off... I've seen people on youtube just do that for new ARs, and my uncle did that after he WAY overtightened everything there.

Also I noticed that after I gave up, for now, and put the bolt back in, the mag wouldn't insert 100%.  It was just barely lower than it needed to be seated.  It was just kind of like a little hiccup thing.  I locked the bolt back, pushed the mag into it's normal position, and closed it.  After the first shot, it functions perfectly again.  Is this a normal thing?

I got all my FAB furniture onto the lower.  Very happy so far :)

Or maybe I should just keep it like this for a while.  I think it actually looks pretty cool the way it is lol :P

There IS thread locker on the barrel nut!

Unless you get it very hot and softened you're liable to twist the multi-part upper receiver into several non-repairable pieces.  You may have already damaged the gun if the magazine won't fit...

Do a SEARCH, there are details on this as well as the damage from not melting the LockTite.

Heat the barrel nut up, keep everything assembled and lay the gun flat on its side with the dust cover (ejection port) side up. I like to hang the barrel nut off the edge of the table/workbench so the receiver is as flat as possible. With an armorers wrench give it some good pressure and if that doesn't get it, give the end of the wrench a good whack with a hammer to jolt it loose.

The mag is fine now, and the bolt moves freely.  As near as I can tell, there is nothing wrong with it really.

What about using a heat gun vs. a blow dryer?  Should I worry about the hop-up and inner barrel melting?

A blow dryer doesn't quite get it hot enough to do any good. A heat gun for a few minutes should be about right, but just give it a hard tap to break it free.

Alright I'll hit it with the heat gun and try the table method tomorrow.

Please remove the inner barrel and hop-up unit before trying a heat gun.  Giving the end of the wrench tap with a ball-peen hammer should break the seal after the delta ring assembly has been heated with a heat gun.  Note, if you don't do this correctly you may very well break the upper receiver.

Inner barrel is secured with two set screws (top and bottom)?  Then just drops out the back?

I got the nut off, without damaging the receiver.  Two people makes it a lot easier.  I didn't know to remove the inner barrel first because the pinned tear down guide shows it being done after removing the outer.  But, everything looks fine so no harm done.

How do you remove the inner barrel before removing the barrel nut? Is there some sort of trick that I'm missing?

Edit: I just want to be clear. This is not snide or sarcastic. I'm genuinely interested because something is wrong with the hop-up on my Noveske upper. It's going to be a b*tch to get the nut off and then properly time the rails again. I've been putting it off until I've got the nerve to deal with all that.

I'm sorry, it was late and I was answering as I would have if it had been an AEG.

I responded to that above.  It was a long day yesterday....
