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 ASL+ series rifles are also covered by the Valken 1-year bulletproof warranty.
