Many of today's AR-15 upper receivers include a forward assist already installed, so if you've received a completely stripped upper for your build, you might be frustrated by the lack of these parts. Worry no longer! CMMG has AR builders covered with the company's Forward Assist Kit. Of course, the kit includes the forward assist assembly, but the spring and installation pin that can be difficult to find on their own are also wrapped up in this complete, ready-to-install kit, ensuring you can get your AR-15 upper into action quickly and easily.
