Vortex Optics Defender CCW 6 MOA Micro Red Dot Sight - out of box fit to Picatinny & Shield RMSc footprint. Just 41mm long and 26 grams. If your firearm uses a different footprint (e.g. OEM cut for RMR, Docter/Noblex, Holosun 509T, or other proprietary optic cuts), you will need an adapter plate to match the RMSc (or Picatinny) base of the Defender-CCW.
