The Speed Bead(TM) System is the FastFire 3 with 8 MOA dot, and specially designed Speed Bead mount.
It is available for a variety of shotguns. The Speed Bead(TM) mounts a FastFire(TM) optic between the stock and receiver of many popular shotguns. Your line of sight will fall naturally just above the vented rib, allowing for accurate and instinctive aiming. At 1x magnification, it's designed for both-eyes-open shooting. That's ideal for shooting clays and hunting waterfowl, upland birds, and turkeys.
