Question about the anti-rotation locks:
Has anyone here had a problem with a properly installed guard that did not have them?
Not talking about extreme use, just trips to the range.
I have not, and do use my ARs for more than just trips to the range.
However, I also install my handguards with Loctite, usually the green 680, between the nut and handguard. The only way the handguard will rotate at that point is if the whole barrel nut loosens, never had that happen though.
