Daniel Defense's adjustable buttstock is constructed of a proprietary blend of glass infused polymers and finished off with soft touch rubber overmolding in strategic points. The buttstock is precision formed for mil-spec receiver extensions to have very little forward or lateral play that is so common in many other buttstocks. This eliminates the need for a tensioning device or friction lock. The buttstock can be run with one of two included buttpads or without any buttpad at all to custom fit the rifle to whatever gear the operator must wear. Its buttpads come in two sizes: a thicker convex shape (0.8) and a thinner concave shape (0.5); designed to keep from snagging when shouldering the rifle. Limited rotation QD swivel attachment points are integrated on both sides of the buttstock for ambidextrous sling connection.
