The Valken ASL Series Whiskey AEG adds several new features to our normal ASL Series rifles. Valken has upgraded the internal components to provide less stress on the gearbox, including a 22:1 ration gear set, piston with full metal teeth, and radial cuts in the gearbox shell. The ASL series also comes with a rotary style hop-up unit with locking increment settings. The Whiskey rifle also comes with new external features, including a newly styled 13-inch MLOK rail, and newly designed molded flash hider. All Valken ASL airsoft electric guns have a 90 Day warranty.
