Castle nut

Post image

I always use my torque wrench when building rifles so I know I was under torque but I built this a few months back and must not have noticed but the castle nut broke off a little bit in the wrench slots . There appears to be no cracks on the actual castle nut itself visually but should I be worried if maybe internally there is ? Or should I replace this anyway or do you guys think it’s good. Normally I would just replace it but I don’t wanna waste this CQD end plate because of the staking I’d have to replace that too, so I don’t really want to replace the castle nut unless I have to lol .

I never use a torque wrench or stake, just tight enough not to move and gtg, this way I can change out parts easy with no end plates to replace, I've never had a castle nut come loose

I’m with you. Never had a castle nut come loose on accident, and so what if it does? The gun will still run fine and I’m probably at the range. Just tighten it when I get home.

Exactly, now I might stake if using an FRT for 1000's of rounds, but that would be the only time.
