Daniel Defense Mil-Spec Collapsible Buttstock, Fits AR Rifles, Tornado Gray 21-091-04179-012 Daniel Defense's Collapsible Mil-Spec Collapsible 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 butt pads or without any butt pad at all to custom fit the rifle to whatever gear the operator must wear. The butt pads 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.
