Almost done with my first ever build. Actually really excited that I'm doing this. But as I continue researching little things (like grease for barrel nut) I tend to get overwhelmed. While searching for aeroshell 33ms grease, I'm reading that grease should be applied to the lower extension (buffer tube) threads. I read the UBR installation instructions and never read about applying grease. Even watched many YouTube videos of UBR installation and none mention using grease or lube on the threads. I torqued the buffer tube to 38ft-lbs. Should I be worried for any potential issues or am I just being overwhelmed and over thinking?

| Torquing down the buffer tube on the UBR is not near as critical as a standard tube. I don't really see any way way it can come loose because of the way it goes together. I do put a little grease on all my threads that dont get loctited. Thats one because I'm constantly putting on and taking off parts. and the easier the better. I also put a little oil on the tube . Some times the outer tube will bind on it if you don't. |

Some times the outer tube will bind on it if you don't. It's always a good idea to put a dab of anti seize grease on aluminum threads. I usually just keep a couple of the little packets around like you can buy off the counter at Autozone. Reduces the risk of galling. |
