This is a used M5 style bottom metal for short actions (accepts AICS or AW type Short action magazines). It is used, but can hardly tell it from new. These normally sell for $165 + shipping. Will sell this one for $130 shipped. Only reason I'm selling is because I switched to a chassis and sold the stock separately from the bottom metal. So I'm not using this. Comes with action screws. PayPal friend payment preferred.
