Fit my AK-AR Stock Adapter + Government Reclassification
I needed a "delta ring" which I was confused at first as to what it was, and had to google around quite a bit, so happy that TrueNorthArms carries this and I love the letter I also received about the Liberal Governments plans to confiscate and reclassify firearm laws, I wrote an email to the Justice department about my agreement with this proposal being an uneducated decision from uninformed government. This Castle Nut is exactly what I needed to complete my AK-AR build, thank you so much TNA, I will be building an M4 very soon and am gonna be buying lots of parts from TNA :)

Great Quality Nut
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.

Good nut
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.

Basic mil spec nut
I bought this to relieve some OCD tendencies (see my review on the buffer tube kit so I don't have to type a yard long). The finish is nice and has staking cutouts.

Very good
Fit and Finnish are very good, I will definitely purchase another. It is a very strong, well machined part, threads are cut well.
