Caddmann, the Matrix arms handguards ( and perhaps others) only require a 1 3/16" wrench to tighten barrel nut. If you want to avoid some of the special tools, it's possible to work around some of them. I've often just used a PMag as a block for workkng on loweds. It works finas lkng as you dont crank it down to hard in.the vise or torque it too much. I think most of us just make due and accumulate tools that make life easier as we progress and build/reconfigure more guns. I think I set the buffer tube castle nut with a flat head screwdriver and a hammer on my first build. LOL.
