i have used a cp one piece barrel 16" .689 caliber, and stock spyder barrel
kingman spyder aggresor
java expasion chamber
spyder xtra vertical co2 adapter
system x 1 piece barrel 14" .689 caliber
e marker electric trigger frame
richocet ak electric hopper
use procaps x ball bronze
Looks really good
14" easy to manuver around the bunkers
Bad long range acuracy
Ive used it with many different types of balls and i have found out matching the ball to the barrel is key. But it still dosent shoot acurite enouph to play long range. I dont think it hase ever chopped a ball. I have used it in nearly every type of scenerio and i have found it to be dificult to use when playing a tournament type fast game on air ball field. But the barrel is very strong ive banged it up alot and it still looks great as you can see in the picture.
Over all i recomend getting a 16" over a 14" barrel due to acuracy reasons. I realized over the years 16" has been more better over all than 14" which is my opinion and how my gun is set up.
