  2. Great Quality Nut
    100%
    The quality of this castle nut is surprisingly superb. It is very well constructed in smooth machined aluminum finish that fits very well on my CNA Mil-Spec buffer tube I also ordered. It does not deform nor damage easily when using an AR wrench tool. It is a great upgrade addition to my custom AR built platform, which I highly recommend this castle nut to compliment your AR.

  3. Good nut
    100%
    What can you say about a castle nut? The sizing was great, it threaded on smooth, and the coating looked good. Put a little lube on the tube threads and torqued it to spec. Stake it in place at the provided gaps and it'll outlast your rifle.

    Installation notes: Sometimes people stake the castle nuts to the end plate for extra security. In that case you will want a pointy punch.
