This is why you stake the castle nut instead of using Lock-tite. Here's looking @ you Rock River! Tube had already been twisted/threads crushed by the customer before he brought it to me:

At one time Rock River did not seem to own a staking tool... or at least it seemed that way.
That is always one of the first things I check on an AR.

Daniel Defense never seems to have a problem doing it. A little attention to detail goes a long way.
 
According to MTdawg, red is what several manufacturers use on gas block set screws. Other than that, I couldn't see a need for it anywhere else.
 
I dont think RRA did that. ( I mean the red locktite ) And I dont think that alot of companies are stalking the castle nut these days.
RRA has been doing that for years. But you're right, alot of companies don't stake these days. Most of them don't use loctite either. But you know who does stake according to the actual specs? Colt, Daniel Defense & BCM. It's an attention to detail thing for me. But there's no excuse for a manufacturer using loctite. Not only is it the wrong way, it actually makes it harder for the end user to service the gun than staking the nut.
