I have a second MATEN upper to build and I cant really find anything I like for a hand guard/fore end. I like the diamondhead stuff, but it looks like its 223/556 only. I have a badger stabilizer on the upper I have now, and I want something different for the new upper. don't really want rails, but that's what a lot of the choices are. Troy, Sampson and Midwest Industries all kind of look the same. centurion ... not sure. anyone know of anything else out there?
