Do you stake the castle nut and if so which punch do you prefer? Yes, you absolutely stake the castle nut. If you USE your gun they can and will come loose. A center punch works best. There is no need to go all hand of God on it, you just want to displace a little metal. Also, it is no big deal to take the castle nut back off should you need to like it is if you use Loctite instead of staking. |

I sold a rifle to my friend. I had built it. Castle nut came loose. I had tightened pretty good. It was cheap stock kit though. Anyway, I helped him fix and stake.
I have a couple complete lowers that I didn't build. They were not staked. SO, not all manufacturers stake. Since the incident, I staked most nuts. It doesn't take all that much like other poster has said. But it makes you feel a little better. And yes, it's not that hard to take off if staked. Little bit of cold blue or aluminum black to touch it up. All good. Loctite may or may not help. Just make sure you clean off the oils from the tube and nut first. sometimes they are coated with manufacturing oil and dry lube. Just don't clean off the dry lube inside tube. (Although I am not really an expert on that.. so perhaps check elsewhere about that). |

No. No point in staking that particular part. I have had plenty come loose over the years. You should either stake or use ONE drop of blue Loctite. I use any center punch handy, I have an automatic center punch, or I will sometimes grab a pointed tap (even though those are NOT meant to be used as a punch an can shatter) they work well and you don't have to hit hard to stake. |
Stake it but you don't need to smash the shit out of it, just enough to move some metal into the cut out area for staking. If yours doesn't have that, just do it anywhere right on the joint.

Later, when it came time to attach my Vltor A5 receiver extension, I put 2 drops of blue thread locker, one on each side of the tube, just before the nut reaches its homestretch, then tightened snugly, no staking. That way, I know that is won't come loose merely from forces applied in service, but for sure I can break it loose with a proper wrench and a lower receiver block, and not too much torque. - CW |
