2A ARMAMENT BUILDERS SERIES AR15 SPRING/DETENT REPLACEMENT KIT, ANODIZE BLACK - 2A-CK-1

Even the best of us have launched half of a lower parts kit across the garage. The 2A Carpet Kit is here to help. We have you covered with some of the most easily lost components that go into building an AR rifle. These parts are stored in a small, secure plastic case to ensure they are not lost in a range bag or a tool box.
