I've got a factory RRA UTE2. I'm trying to replace the reciever end plate and CANNOT get the castlenut off. I have an armourer's wrench with the correct match for the castlenut but it won't budge. I dinged up the threads a little and I quit before I did any major damage.
Does RRA LocTite the castlenut or am I missing something? I just joined and this is my first post so take it easy on me. I've searched and can't find anything to help me on this one. Any information would be greatly appreciated. ––––Matt |

I didn't know if there was a trick to getting it off. It's either cranked down or has something holding it. HEAT... I use a small propane torch to put some heat to the castle nut. You'll start to smell the loctite, that's when you know it's loosed up. Remember that it doesn't take much heat either, don't go melting all your plastic hardware. I also found out after working on a friends DPMS that they also use some sort of thread lock, it was hard/brittle and light green in color. |

A friend of mine is having the same problem with his RRA. The buffer tube is slightly crooked and he needs to loosen the castle nut to rotate it. Nothing will budge it, he has even tried heat and a pipe wrench. Since the nut is marred anyway the next step is to probably have it cut off without damaging the buffer tube.
The one last thing we want to try before cutting is to heat the nut while putting pressure on it with the wrench. Possibly the loctite is cooling before the nut can be loosened. |
| I have not had a chance to look at the friends rifle yet, but he said nothing looks cross threaded. I think maybe it might take the combination of heat and pressure to get this one loose. He has a new castle nut to replace his original if it will ever break loose. If not it might be time for a trip to the gunsmith. |
Don't forget to stake the new one.
