It’s a Solid castle nut
It does what it needs to ,do it works fine It’s not rocket science. You can buy cheaper or you can spend more money. But this works great. My armorers wrench was able turn this nice and snug no problem
Nice improvement over a standard castle nut
Definitely better machined than a standard castle nut. The finish is also smoother and glossier.
Would recommend: Yes
A good looking nut
The product description is accurate, super high-quality, does not scratch or dent while screwing on. Can be used with a fixed stock or multi position.
Would recommend: Yes

Everything you need, nothing you don't!
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

- Ease of installation
Cons:
- None

- AR carbine build

Castle nut
This really makes my charger look nice paired with the brace and tube I bought from optics planet. I called to make sure which one I needed. The person I talked to was very nice and knowledgable. He also took my order over the phone My package arrived in a couple of days. I have never had a problem with optics planet.
Would recommend: Yes
