This is a basic AR grip. These are new, durable grips constructed from quality composite materials. Made by Prudent American / P&S Products, which is a contractor for US DOD rifles.
Note on colors: Tan grip colors are tough to judge. We have a handful (pun. haha) of Tan, Taupe, FDE grips. This one is the darkest that we have, but not quite as dark as Knights Armament Taupe.
Note: This does not include a screw or washer (required). Available here.
