Q's Review of Presma AR Buffer Tube Receiver End Plate Castle Nut

This is probably the lightest nut out there. Expect some deformation if you go to 30ft-lbs per the AR-15 manual spec. I suggest to aim for 25ft-lbs

I would buy another one now that I know, but I fixed the damage to the anodized finish with aluminum-black
Pros:
  • light weight
Cons:
  • None
Best Used for:
  • Light builds
Would Recommend: Yes
