Removing over-torqued castle nut

[elephantrider]

A Wheeler strap wrench is a supplementary tool that can be used in conjunction with the dedicated tools for many items on an AR and should be part of a tool kit. The 'Wheeler Fine Gunsmith Equipment AR Armorers Professional Kit' comes with one as part of the package or the 'Wheeler Engineering Delta Series AR-15 Strap Wrench Non Marring 567839' can be purchased separately.

It can be used for hand guards, barrel nuts, buffer tubes and those pesky castle nuts that can be marked up.

Still looks pretty meh to me. I don't see that working well on much besides the example shown. I don't really see the need.

Something to also keep in mind is that of wet torque and dry torque.
Torque values are given as dry, unless otherwise stated. Luring the threads of a fastener generally reduces the friction buoy 20-25% depended the upon the lube used.

For the OP, the anti-seize would have increased the actual torque applied by 24%. If torquing a fastener that has been lubed, the torque value most be reduced. The only fasten on an AR that has a wet torqu value is the barrel nut.

Looks like that barrel nut was just beyond hand tight. The vise isn't even mounted. I have and do use a strap wrench similar to that one. It does have its uses, but I can't see it effectively removing a properly torqued barrel nut.

The carbine castle nut and the rifle receiver extension also have a "wet" torque value.

I'll be darned........It sure does! I never noticed that before. Thanks for the correction.

Good catch. I had noticed that, but never associated it with "wet" versus "dry" torque values. I have that reference at p. 3.81.1 of my 1991 TM copy. I understand there is an update from either 2008 or 2011. Do you know where that might be available? I have searched but my Google-fu may be off.

I have a copy of the 1991 TM and the newest one I have ever seen was from 2008. I never saw the 2008 version in print with my own eyes though, I only saw it because someone posted a link to it on this forum and it was later removed. > https://www.m4carbine.net/showthread...t-pounds/page2

Just scroll down to post #13 by a0cake. That was the link that used to go to the 2008 TM.

Shoot me your email address, I'll send you a copy of the Nov 2008 TM IF it will "fit".

5. Using combination wrench (7) (WP 0039, Figure 23, item 10) and torque wrench (16), torque lower
receiver extension (4) to 35 to 39 ft-lb (47.25 to 52.65 N-m). Torque is read when both wrenches are
used together.

6. Lubricate threads of lower receiver (2) and lower receiver extension (8) with molybdenum disulfide
grease (WP 0045, item 18) before reassembly.

Cut off wheel the nut and split it?

Considering the topic of this thread does anyone know where the hell I can find a geissele reaction block?
