Can get Stainless Steel back and inserts and new size fronts 10-18"
The aluminum back and inserts arent very durable
You can switch out the bore size to fit the paintball you are using exactly. You can also buy fronts to switch length from 10-18". If you buy a new gun you can buy a new back and keep the fronts and inserts. The stainless steel backs and inserts are a must. The 10" front is great for speedball and the 18" is the quietest front i have ever used. There are 8 different bore sizes to fit the paintballs you are using. The barrel with a back, insert, and a front is about $110. The entire aluminum freak kit is about $180 and the stainless steel is about $210.
A definite must for any gun. A barrel makes all the difference especially this one.
