Pat's Review of Guntec USA AR-15 Heavy Duty Wide Castle Nut For Car/M4 Buffer Tube

It's a heavy duty end plate. Screws on tight, stakes easily enough, feels durable and as strong as can be. Mounted properly, this thing won't come off unless you really want to take it off. No need to waste the money on any other castle nut, stick with this one.
Pros:
  • durable
  • Heavy Duty
  • Strong
Cons:
  • None
Best Used for:
  • Keeping your receiver extension and end plate securely locked in place
Would Recommend: Yes
