| Is there any way you can screw one of these things up where it cant be used? Just was curious after having to bow up on my new LMT lower that was staked to put the new Magpul ASAP sling plate. She's not that pretty anymore but she's on there. |

Endplates yes, but I have never staked the actual castle nut just the endplate. the endplate is just so soft I just use it. So did you stake the ASAP and would you consider that disposable?  Nope the ASAP has a little metal key that is suppose to take the place of staking. Plus its cast so I really wouldnt want to try to. |

Uh no, that "key" replaces the nub on the normal end plate, it does not prevent the castle nut from loosening. |

I have heard of castle nuts so firmly installed or glued in place that they had to be cut into pieces to remove them.
End plates are the pieces distorted by the staking not the nuts but I have seen many endplates chewed up by poor fitting wrenches. Since endplates and nuts are cheap, I personally consider them disposable and replace them any time I replace a tube. Some of the tricky things people are passing off as endplates are not made of good materials and they will crack if you attempt to stake them. |

If I could destroy one I would be on worlds strongest man! Just one of those things where I was wondering if it was even possible? Someone will eventually chime in with something. I know one thing for sure, Im ordering a new stock wrench before the next one. It is extremely easy to destroy castle nut without the right tools - this is what i have managed to accomplished in field like conditions with channellock... http://i399.photobucket.com/albums/pp71/robert60446_r/AR15M4Tube.jpg It is also very cheap to replace - buffer tube too....

The metal displaced quite easily and seemed soft. |

Uh no, that "key" replaces the nub on the normal end plate, it does not prevent the castle nut from loosening. Step 5: Install Locking Key Select correct Locking Key for your type of Receiver Extension(Short=Military or Long=Commercial). Using a pair of needle nose pliers, install the Locking Key, with the long axis in a vertical position, into the ASAP plate keyway to engage the receiver extension. Hand tighten the locking nut down to prevent the key from moving. I assumed this step was meant to take the place of staking but i could be wrong. |

No, as I said that "key" replaces the nub on the original plate. Take a look at your original end plate.. Now when you took off your extension to install the ASAP, the tube, nut, and plate all turned. Right? Now if you installed the ASAP like the Magpul directions, you put the ASAP to the backside of the lower and then threaded the tube into the lower thru the ASAP. Then you put the key in to lock the ASAP to the tube. Without staking the castle nut can still back off.

He's right, it still needs to be staked.
That key is just to keep things aligned. A stake job is super important on the ASAP cause now it's being worked not only when the gun is firing but also when you sling the weapon. At least that's what I've currently ran into, I installed the ASAP plate about a month ago. |
