Works greatQuality nut great finish

Great Quality NutThe 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.

Good nutWhat 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.
