   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

   I bought this for a new AR built . It’s worked just fine . Did not see a lot of differents in this heavy duty and a regular one . It was about the same price as a regular castle but. I have build dozens of AR’s , I would buy this item again .

   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.

   The guntech buffer tube castle nut was a great buy! This particular castle nut has crisp threads for ease of installation. The nut went right on and secured my end plate with ease. It was easy to tighten and stayed put with rugged use! Great product at a great price and I will definitely buy again!

   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.

   Definitely better machined than a standard castle nut. The finish is also smoother and glossier.
