I can't seem to loosen the cap (castle nut) that holds the buffer tube on my Colt M4......Do they use Loctite?  I have the proper wrench to do this, but it wont budge.

Any help would be appreciated!

It might be staked.

How have you been trying to remove it? With a standard 1 tooth CAR-wrench? I busted mine trying to remove it off my factory 6-position bushmaster. I then bought a 3 tooth wrench and heated up the reciever for a while, and it finally came off. Just needed some serious leverage.

No............I have the proper 3 tooth wrench.

It looks like it has been permanently attached.  The 'teeth' of the castle nut appear to be joined with the teardrop thingy.

I was able to use some good old manpower when I had one that was staked on, but the dremel idea would be a big help with the right bit. If worse comes to worse, you could sell it to me for $10.

Ok...........I figure it out.  I had to go in like a dentist with the dremel tool and grind out the 2 areas that were 'staked'.  

I don't see why Colt needed to do this.  I have never had a nut come loose before.  It really made this more of a project that it should have been.

Anyway, if any of you need dental work, I am pretty steady with the Dremel tool!

To make sure it stays on.

Maybe you don't treat your ARs as rough as other Colt customers....

Come on now, I treat mine pretty rough and none of them have ever come loose.

Nice work samian!

Somehow I doubt your jumping out of planes, or having it get bounced around in the back of an APC all day.  Vibration is a bane to all things screwed in place.
