Like new Holosun 507k X2 Green.  Shake awake, multi reticle 2MOA dot, 32 MOA circle, or circle and dot.  Mounted once and sighted in, carried a little, shot a little. Excellent conditions, no problems at all with it.  Comes with 2 of the 3 original sets of screws for mounting, everything else new in box (manual, sight adjustment tool).   *I have a large collection of new screws of different lengths, thread pitch etc for about any pistol optic mounting solution possible if the 2 holosun ones don't work on your gun.
