This is a used Aimpoint 11830 and LaRue LT660 combo.

The Micro T-1 can also be used by hunters and sport shooters who need night vision compatibility. The performance of the Micro T-1 is optimized for use with all generations of night vision devices (NVDs), but is ideal for 3rd generation night vision technology.
LaRue LT660
Like all LaRue mounts, they are precision-machined out of bar-stock aluminum and matt black anodized to provide a durable non-reflective surface finish. The locking LaRue Speed Lever provides outstanding return to zero; the optic can be removed, and replaced, without loss of zero.
