Full description


A compact rail piece for Airsoft 6mm G-Series pistols that replaces your rear iron sight, leaving you with a 20mm rail for the attachment of optics or other accessory combos you can dream up. The rail piece has a central channel meaning you can still use your front sight should no optic be attached, however just watch out that you'll be aiming slightly higher than without it! The rail piece comes included with an ambidextrous cocking lever that you can install either side of the rail to improve grip and reload times by giving you an easier surface to grab when manipulated the slide.
