Ron's Review of KAK AR-15 Mil-Spec Castle Nut

I ordered 2 for 2 separate builds and both of them would not work on a mil spec buffer tube and a aero precision enhanced buffer tube. The treads on the castle nut were trying to strip out my buffer tubes. Does not work. I do not recommend these.
Pros:
  • None
Cons:
  • Does not work as stated
Would Recommend: No
