Dye boom sticks are an excellent barrel for any gun. They are made for almost every gun that is out there and are in 10, 12, 14, 16, and 18 inch sizes. These barrel will make and gun extremely quite and are very accurate. They are made by Dye Precessions and are half stainless steal and half black aluminum. They usually go for about $105 and believe me they are worth it. They can be found at almost every paintball store.
