Not sure I would label this as "Extreme Duty" as there is probably less actual threads grabbing your buffer tube. However, they look cool for sure! Nice little touch if you're doing a custom build and want those small differences that really set a particular firearm apart. Finish starting to wear some on my older one but just has a brass looking rub through on the edges and I think it looks almost better that way. I have bought two now so obviously happy with it.

I purchased this for use with a KAK buffer tube and it did not fit at all! The nut threaded on but, not nearly far enough for the buffer tube to catch the detent. I wound up using this for another project with a standard milspec buffer tube. It did fit and I felt confident that it would not back off but, the collapsable stock will to go to the shortest length of pull (milspec or Magpul), the tips of the nut scratched the finish of the buffer tube, and neither of my armorers wrenches fit properly. Again, I don’t think it will come loose but, I won’t be purchasing another nor recommending this product to anyone for a future build. I gave it 3 stars because it does appear to hold properly (range time will tell) and the threads were good but, it’s not really worth the trouble. A standard castle nut will suffice and costs less anyway.

Just like other guy says won’t work with a lot of buffer tubes I had a WMD and wouldn’t screw on far enough for buffer tube to catch the retainer won’t be able to use. It should have that in the description will I only work with certain buffer tubes

Greatly priced, Looks awesome with a colored buffer tube showing through. Be careful when tightening with your wrench, it can get marred. Definitely will be buying more of these. Shipping was fast as well.

The black finish on this castle nut is metallic looking & comes off fairly easy but overall it’s aesthetically pleasing.
