    Sorry, I already sold all of my guns per your advice Patrick. No mil-spec or commercial buffer tubes to swap here.

    No criticism on staking the end plate/castle nut, as it makes sense on a hard use item. I just wonder how many folks building their own do that. I have on a few over time but for the most part just tighten it and forget it. In almost 3 decades of working on these, I've never had a castle nut come loose either. I've seen with or without staking from company built ones. Who stakes, who doesn't and why?
