When we set out to design our own rifle stock, we knew it had to offer multiple configuration options right out of the box.We considered each way a person might need to shoulder their firearm, whether wearing gear or not and the range of adjustment that a person might need.We ended up with is a collapsible stock to 6 lengths while in the shooting position and engineered to be california compliant with the insertion of a single roll pin.Ambidextrous single magpul qd sling mount attachment point, two standard sling attachment points and removable lower portion allows for reduced size and weight or installation of optional metal strike plate.Type: ModularFirearm Type: AR RifleFirearm Model: AR15/M4Finish: BlackAdjustment Type: CollapsibleSwivel Studs: 2
