NCStar Three Rail order Sighting System Green Dot/Red Laser

Product Name: NCStar Three Rail order Sighting System Green Dot/Red Laser
I order have 2 spares of these. They look big and bulky, but are super lightweight and have quick detach mounts and despite how it looks once you try it you'll understand why I keep extras. Honestly the 3 rails are about as useful as teets on turtle, but the optic itself has a great sight picture and has held zero perfectly on my blackout for over a year and I get it out frequently. Ships fast and free, securely packaged, arrives as shown. Easily visible reticle is green, well-powered laser is red. Case, djustment/sighting screwdriver, battery and instructions included.
