Updated: I had a picatinny rail and shell deflector welded on, as well as swapped out the stock and handguard for some nicer ones. It is still heavy, but works really well.
I put a Vortex Strikefire 2 and 4x magnifier on it so that it had a bit of an optic. The low price for mags is awesome. They basically run about $4 a piece.
My overall thought is that it will be a hell of a battle rifle if needed. I would hate to hump it around along with the heavy arsed .308 rounds, but in a defensive type situation it would be amazing.
