I currently use an 99 Angel SE with 12in carbon fiber barrel, DYE trigger guard, liquid bolt, adreanlin trigger, KAPP high rise feed, and a PMS 68 4500 nitro tank
new gun, But seriously get a new barrel, and an evolution bolt.
It is smooth accurite and efficent, the gun is also quiet and has a nice snappy triger
It is ANS (anus) the gun ran great for six months or a year but after that watch out. The timing will go to crap the frond block hoses will start blowing off the seals will fail and you will look at it and realize how lottel ttime and effort went into the cheap crappy componets.
I am not denying it is a high preformance gun that is nice right away but the long term relibility leaves a lot to be desired it dose shoot well at first but in the long run just buy and Angel.
