Spyder Shutter Java with Smartparts16" Big Daddy barrel and Tasco Bantam shotgun scope.
PMI Marballizer, PMI Premium
Shoots very accurate, and farther than stock 12" barrel. Great design.
Decreases velocity by about 25fps.
I have been using this barrel almost the length I've had the gun, about two years. Its accuracy, quietness, and distance will bring any opponent out in one shot. I like to play as a sniper and it does the job quite well. The porting on the barrel adds top spin to the paintball with increases distance. I am amazed how quiet the barrel really is. I also have a Tippmann Pro/Carbine with a stock barrel that is somewhat loud when shot. The Big Daddy barrel sounds like a silencer. There is nothing I can think about that is negative about this barrel. It is a definate buy for anyone.
Although Smartparts does not make this product anymore, try to find a used Big Daddy barrel. It is worth it.
