Tired of moving your cheek rest to remove your bolt? Or trying to fit your rifle in a normal case? Or waiting for a hinge to be made by you know who? So were we. This hinge was born from an need, and focused on a simple solution. This adapter set utilizes a the Magpul** hinge(not included), the dimensions of the hinge are near perfect, so to speed up delivery we opted to adapt to it rather than start from nothing. This Adapter Set has limited availability but we are working hard to keep the stock flowing!
