I had a lower put together by a gunsmith and he staked the castle nut by deforming the threads on the buffer tube. Does that work? I staked a different lower myself and never heard of this method before.
youre only deforming 2-3 threads at most.....itll keep the castle nut in place, but with a some muscle, you should be able to get the castle nut off no problem, the nut will chase the threads as you screw it over the staking.the normal way of staking can be fairly easily UN-staked. it's not immediately clear how one could easily clean up those threads enough to ever take the stock off. offhand, i'd say that method is a bad idea
I have to agree here. Not that smashing a few threads won't work and I believe the castle nut or receiver extension nut with some force will chase the threads but it just seems a bit hokey to me for want of a better word. There is a right and wrong way to stake the nut and smashing a few threads just does not set well with me as good workmanship or a good work habit. Will it work? I guess yes, it will work.the normal way of staking can be fairly easily UN-staked. it's not immediately clear how one could easily clean up those threads enough to ever take the stock off. offhand, i'd say that method is a bad idea

TO THE OP, you need to learn to be your own AR gunsmith, the AR-15/M4 and clones are not rocket science, they are just common tools of our trade.., "fun with guns". ...
For most of us the nut doesn't have to be staked. If it's torqued correctly it won't come loose. I don't stake mine simply because I want to be able to take things apart more easily.
However your was not staked properly.
