Target Adrian Lewis Black 90% Swiss Darts. Precision Milled - CNC milling machines are used to create advanced and intricate grip designs. Radial Grooves - The barrels consist of contemporary radial grooves. Performance Coating - Features black PVD performance delivering enhanced grip. The Target Adrian Lewis Black 90% Swiss, which has been endorsed by Adrian 'Jackpot' Lewis, is a continuation of Adrian's existing playing barrel with the addition of performance coatings and precision cuts. The barrel is made of 90 percent tungsten and is decorated with a combination of CNC mills and radial grooves throughout, which is then coated with a black PVD finish. By re-machining the barrel and overlaying a beautiful blue finish within the grooves, Target was able to achieve a striking contrast. Complete with a black Pro Grip shaft and an Adrian Lewis black Signature flight, this dart is ready to play.
