Quality castle nut

Love how you have more gripping area on the nut more than just your stock notches.

Dark Hour Castle Nut

by theguyucantc, Verified Owner from MI, United States Written on April 16, 2024
Product itself is, in all likelihood, suitable for its task, however…. The picture does not match the product, and that was disappointing…. I was looking for a well QCd part with some kind of material pedigree that still looked like a regular, no nonsense castle nut. This has extra machining that deviates from the pattern of a traditional castle nut and is not what I thought I was buying.
Pros:
  • Material pedigree
Cons:
  • Unneeded frilly machine work
Best Used for:
  • Instagram guns
Would recommend: No

Looks nice, just different than expected.

This is a nicely machined castle nut, however, it is different than the picture. Like the V seven castle nuts, there are wrench slots all around the nut, not just the normal 4 that are pictured.

It doesn’t look horrible, it just isn’t as subtle as what is pictured. I was looking for a clean OEM look, but it’s okay.
