We have devoloped a bottom metal that improved many of the problems we have seen with other metals on the market. Our bottom Metal holds a flush magizine as desried on most hunting rilfes. We have have improved the spring and release latch for easy drop of the magazine. With an andjustble latch to ensure rattle and clanking of the magazine have been eliminated. No one wants to remove the bottom metal to adjust trigger pull weight, we have adressed this as well.
