SR30 Lower Receiver Assembly Kit, SR-30 IWS


The ambidextrous bolt release, selector lever, and magazine release offers left-handed users the ergonomic advantages inherent to AR15-based controls. The drop-in KAC two-stage trigger serves double duty as an aid to precision marksmanship while enabling surgical speed shooting at close range.  I have added a new SBA3 Armbrace and 1-mag to the box. When you get this home you can assemble the 2 parts as a pistol for now. If you pin and weld the flashider you will have a legal over 16 inches long barrel rifle. Since it is registered as a lower at your dealer, you can use this lower to complete any pistol project or with any 16" or longer barrel upper to complete a rifle.  Always check your LOCAL LAWS FIRST! Before you get in trouble, These items ate not legal in all 50 states and Territories!
