An old friend came to my place to learn several things related to AR-15. He wanted to gather enough information regarding the gun before buying it. Besides this, we talked about iron sights, paddle stocks, the process of zeroing, and much more. One important thing that we discussed last night was castle nuts. At that time, my mind suddenly remembered that I hadn’t discussed this topic with you people. However, it is important to know about this locking device. So, I went through your comments and queries and found out someone has already asked about castle nuts.
Furthermore, another reader was concerned about the staking process. The staking process excites me. So, I decided to share my two cents on this point.
How to stake a Castle nut correctly?
I searched about the staking process on YouTube. It is because some of my readers understand better with visuals. I found a channel called Gun News and Reviews. I must say this is the channel of a pure gun enthusiast. The man guided me so well about staking the castle nut that I decided to share this video here.
You can watch the staking process of the AR-15 castle nut. But don’t you forget to come back as I have some special tricks and tips for staking a castle nut within three minutes without any hustle.
What is the process of staking a castle nut?
Staking a castle nut leads to the transference of material from endplate to castle nut notches. This transfer is done by mallet and punch, leading to castle nut immobility. You can find loosening the castle nut difficult as it is perfectly fastened. But it is not impossible to undo it with a castle nut wrench.
When using an AR-15 for a recreational purpose, you don’t have to worry about improper stacking of castle nuts. However, if your AR-15 is for defense purposes, then watch out. Learn the procedure properly because it could be a matter of life and death if the castle nut is not torqued and staked in two places.
What is the importance of castle nut stake?
If you own an AR-15 like me, obviously, you know the importance of staking a castle nut. I use an AR-15 for self-defense purposes because of its accuracy and efficiency. One who owns an AR-15 knows that a loose castle nut will bring catastrophic failure.
The drawbacks of untightened castle nuts lead to loss of endplate. The loose endplate could become the reason for the detent falling out. After falling off of the detent, the receiver can move easily. As a result, the receiver will lose the ability to retain a buffer in a place. A buffer and buffer spring will be displaced, which could be the reason for the AR-15 explosion or breaking of the receiver.
Many people who own AR-15 do not know the importance of staking a castle nut. I would like to remind those people that a catastrophic failure can happen in a minute or two. So why are you taking a risk?
