I have a 10vt that has a bottom bolt release with plastic frame around the mag and trigger guard. I really like the rest of the rifle and have done some upgrades, have the optics i want, loads that work in it, but the plastic frame around the mag seems kind of cheesy. Did they ever make a factory gun with metal bottom that uses a bottom bolt release? I dont really need a detachable mag i dont mind a hinged floorplate but i would really prefer the replace the plastic with metal if i can
