| Hi guys, I am new to AR15s, and I recently ordered a Magpul ASAP mount. I also purchased a tapco castle nut wrench, but there is a problem. The castle nut is on there incredibly tight, and I am wondering if there is any tips or tricks to get it off there. |

The castle nut may be "staked". Check to see if yours is staked... if it is, you will need to break the staking job first.
If it is not staked, you may have loctite on the threads. I think that RRA may use loctite on the threads... Also, you may want to find someone who can lend you a higher quality castle nut wrench... |

Brute strength lol . A vise block would help . Ive always just done it using the grip of the gun as leverage . with the gun assembled i lay the gun on its side on my bench and the grip basically provides leverage as it digs into the bench as you turn the nut off . the gun can turn only so far before the grip begins hitting your bench . you wont be able to turn so hard your grip goes through your bench . Its hard to explain but it works quite well .
A longer grip on your wrench would also help generate more force . Like a piece of pipe . Ive done it with and without a vise block and neither have given me problems . Sorry for the crappy explanation . Its one of those that if i showed you you'd say "oh! I got it!" lol Good Luck |

For Loctite 242 Disassembly:
1. Remove with standard hand tools. 2. In rare instances where hand tools do not work because of excessive engagement length, apply localized heat to nut or bolt to approximately 250 °C. Disassemble while hot. |
I also have an Oracle, and I just put on the ASAP last week. It was not staked, but using that wrench without a lower receiver vice block is just wasted effort. Once that thing is locked down in a vice it should twist right off and you'll have no more problems. It's also a good tool to have laying around just in case

Thanks. Yes Brute strength and a solid wrench usually breaks the staking, but if not you could use a hammer and punch to push some of the material out of the staking slot. |

The Hammerhead Tool company makes the best castle nut wrench that I have seen. Hammerheadrifletool.com I read some reviews that said this wrench will not work with the Magpul ASAP due to the bar with the ring. Can anyone verify if this is true? I ordered the ASAP, and need a wrench to install it. |

| I'm going to order the ASAP for my Colt but I'm abit nervous reefing on the castle nut to break thru the stakes. Since I won't be using the old plate, I'd almost rather use a Dremyl with a thin cutting disc to cut a slot in the plate next to the stake and then tap the stake back into that slot. Someone somewhere suggested this and it seems to put the least strain on the buffer tube. |

However, if done correctly, your not going to damage the receiver extension (buffer tube) spinning the nut off. A good wrench like the HammerHead makes removal easy. |
