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 :)
Quality nut great finish
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.
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.
Fit and Finnish are very good, I will definitely purchase another. It is a very strong, well machined part, threads are cut well.
