JC's Review of JE Machine Tech AR-15 Mil-Spec Castle Nut
Same as a million other castle nuts- put it on the right way, don't cross thread your buffer tube, and it'll do the job! Some people believe in peening the threads in one of the slots of the nut once it's tight, but that will make swapping tubes difficult- not impossible. I prefer to put medium loctite under the castle nut to stay put.
Pros:
- Inexpensive
Cons:
- No frills
Best Used for:
- Any ar build, not necessary for a2 fixed stock tubes
Would Recommend:
Yes
