Buffer Detent - Deep Enough

Agreed.

Snug it up, put some clear nail polish on it if it makes you feel better, and make sure the detent moves freely, yet has no chance of coming out.
 
Some people feel that everything must have some sort of thread locker on it. So I'd recommend the weakest of all, clear nail polish, for this. In reality, the way the buttstock assembly goes together puts enough tension on the buffer tube that is not going to go anywhere. The stock fits against both the receiver and the buffer tube, effectively locking the buffer. But, some people insist on some sort of thread locker. Just don't use LocTite. Please.
 
As long as the buffer retainer is captured by the tube (ie. it doesn't shoot out of the lower), you are fine. The main concern is that the tube isn't screwed in one thread too far, preventing the lower from closing. Also make sure that the buffer makes contact with the back end of the bolt carrier before the upper fully closes on the lower. You are looking for constant contact where the bolt carrier actually pushes the buffer rearward slightly as the upper is closed. This ensures that you won't get any bolt bounce during operation.
 
IF you properly stake the castle nut, then why would you also need thread locker?
 
I put blue thread locker on my castle nut when I installed a new QD end plate last week.

In fact, it was specifically recommended (if your gun sees full auto...but I'd rather be safe than sorry) by the instructions included with the end plate (from Daniel Defense).
