Complete Garbage by SST, Verified Owner, December 22, 2021
Thought it would be strong and look good, Grooves are rounded so the moment you put any weight to tighten it slips and the material breaks easier then any castle nut I used before. With the crappy material and the rounded groves its a bad time. As we...

nice fit A+++ by Hobie, Verified Owner, July 20, 2025
Nice fit for a flat buffer tube end plate. Threads where perfect for the tube. I got the aluminum colored one for contrast . For the recessed buffer plate it is hard to fit wrench on to tighten buffer tube nut but can be done.

Wrong color or lack there of by JP, Verified Owner, December 29, 2024
I ordered this in gold. It arrived and was at best dark orange. Instead of dealing with customer service, I painted it myself, which I was trying to avoid. Oh well, here we are and at least it is the right color.

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-...

Product Info for Presma AR Buffer Tube Receiver End Plate Castle Nut

The AR-15 receiver end plate/buffer tube castle nut is used to connect the buffer tube to the receiver and prevent any type of nipples from slipping off. This durable receiver end plate/buffer tube castle nut is machined from 7075 T6 aluminum for a strong lightweight platform. The machined receiver end plate/castle nut helps prevent any unwanted nipples from forming and is a crucial part of overall receiver installation. This receiver end plate/buffer tube castle nut should be installed at each end of the buffer tube instead of each individual end of the buffer tube. Please refer to your manual for proper bolt removal/adjustment.image
