I love this model of the Mountain rifle. I wouldn't replace the bottom metal I would sand it or blast all of the paint off clean real well and cerakote it or duracoat it. Heck I've even used regular spray paint and top it with a matte clear and let it set for about a week. Floor plate is still scratch free. I would use the 2.5-8×36 but that's my favorite little setup with talleys.
