Daniel Defense Collapsible Black Buttstock - The Daniel Defense adjustable buttstock is constructed of a proprietary blend of glass-infused polymers and finished off with soft touch rubber overmolding in strategic points. The new 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. All of this results in a durable buttstock that will give the shooter a comfortable and repeatable cheek weld and unprecedented control of the firearm. 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. The 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 an ambidextrous sling connection. 7 -Inches Long 5.5 -Inches Tall 1.75 -Inches Thick Weight: 0.50 lb For Mil-Spec receiver extension tubes
