The American Defense Delta Ring Cap is an optional accessory that replaces the top ring on your delta scope mount, allowing for the seamless mounting of a red dot, laser aiming module (LAM), range finder, or other accessory at the 12 o'clock position. You can mount a red dot to use as a backup sight, a night vision passive aiming option, or a complement to a high-magnification scope. Mount a LAM or range finder using the 7-Lug Tall Picatinny cap to shift the center of gravity of the firearm rearward, have sighting solutions mounted on a rigid platform, or have all the controls within reach when mounted on the firearm.
