I currently have a Prometheus 6.03 Tightbore, Prometheus soft type hop bucking, and a PDI 170% spring in my CA M16. I'm finding the tightbore didn't help accuracy as much as I'd hoped and I'm looking for a way to improve accuracy and a little extra FPS. Right now it's shooting about 320 with .25s and I'm trying to keep it under 375 with .25s. I've been told to get a Prometheus type A cylinder, Prometheus POM piston head, Deepfire full tooth piston, Prometheus version II cylinder head, Prometheus sealing air nozzle, and a Systema torque up. Anyone know if this stuff'll help?
