Effortless! Hitting great shots with the new Bazooka QLS irons is easy. Combining a large undercut cavity and super-wide sole, the QLS is remarkably stable and forgiving. Added to the design is a shallow face that lowers the center of gravity, so every shot with these irons fly higher, straighter, and land soft. In addition to its forgiving design, the QLS gets its powerful distance from its cast 431 stainless steel head. The super-thin face is only 2.2 mm thick, launching the ball quickly and efficiently for maximum performance. The QLS irons are fully interchangeable with the QLS Iron-Wood, both sharing the same appealing top line. Now you can mix and match QLS irons and Iron-Woods to build your ideal combo set.
