i3auer's Review of Sniper AR-15/M16 Receiver Extension Mil Spec Castle Nuts

Weighs the same as my steel castle nut that is almost identical. All my other Aluminum parts weigh nothing compared to this, so if it is as described, it should weigh much less. Feels like steel and surprised they'd ship something that's starting to show signs of rust in the bag.
Pros:
  • Looks like a typical Steel Castle Nut
Cons:
  • Not as described.
Best Used for:
  • Cheap heavy rifle
Would Recommend: No
