Brownells AR-15 A2 Stock Spacer Features The Brownells AR-15 A2 Stock Spacer is machined from aluminum to serve as a replacement spacer between the buffer tube and a rifle length A2 style fixed stock. This component helps ensure the stock seats correctly against the receiver extension maintaining proper fit and preventing unwanted movement. Because it is built to fit standard rifle length buffer tubes it works as a direct replacement for a worn cracked or missing factory spacer. Keeping this small part in good condition helps the buttstock stay solid and secure through repeated use. Finished in black aluminum this spacer is built for use on standard AR-15 rifle length configurations and installs easily during a stock rebuild or repair. It is an inexpensive part that is easy to overlook until the stock starts to feel loose or misaligned. Builders restoring an older rifle length AR-15 or assembling a parts build can use it to complete the buttstock assembly correctly. The Brownells AR-15 A2 Stock Spacer is a small dependable fix for keeping a fixed-stock AR-15 solid and properly fitted.
