First off, hello all. I've been lurking for some time now and I finally have a reason to introduce myself.
I have little to no technical knowledge of the AR-15. I'm a new owner who snapped together a BCM upper and a PSA blem lower. That said, from what I've read castle nut staking is a must. I was recently comparing two PSA blem complete lowers to a BCM blem complete lower and I noticed a difference in castle nut staking.

Is the PSA staking sufficient? I'm not posting this to bash them, but it doesn't look anywhere near as staked as the BCM castle nut (only 1 out of 3 positions and I'm not sure how much metal is really pushed into the groove). Would you guys recommend I stake the PSA castle nut myself in the areas where there is no staking?
I should note that both PSA lowers have the same staking and have been absolutely reliable after ~250 rounds each.
