Maybe this has been done before here, but I went back a ways (probably not far enough) and didn't find anything on this topic, so here goes......
I am a bit old school, hard headed, and possibly a bit retarded, but I tend to want a pinned gas block on my ARs. Mostly due to my not having to worry about screws loosening up, the tolerances changing due to heat (aluminum blocks), and other things going wrong at the worst time. I have had nothing but milspec front gas block sight towers on all my previous builds, and now was going to have my current build redone with a pinned front sight tower to make it "pinned" and not aluminum. I just found out that my low profile gas block is actually steel, but is screwed on to the barrel.
My question is: would just pinning the current block work as well as a milspec gas block that I have cut off, or just do the work and go to the milspec gas block? A third option that I want to know is.....using the factory low profile block, how about making sure everything is correctly installed, and then stake the screws to keep from having whatever version of loktite is used from releasing (heat or water immersion)?
