2k cocker w/ 12" DYE Boomstick, Silver MacDev Gladiator, ANS JackHammer 2, DYE Hinge frame, AKA Lightning Bolt, AKA Tornado Valve, MaddMan Spring kit
This increased my efficency about 700 shots on a 68ci 4500psi tank. It makes my cockers consistency +-1fps with my Gladiator regulator. Makes my gun so quiet all you hear when i shoot is the ram cycling(To hear what it sounds like i turned off my jackhammer by backing the screw all the way out and pulled the cocking rod and fed a ball into the chamber and its sooo quiet) And i have broke RPS balls which were 3 months old out of about 2 cases which is very pleasing.
It requires various different upgrades to get it to its full potential such as a High Flow Regulator(MacDev Gladiator), a High Flow Bolt(AKA Lightning), a light spring kit(I use maddman springs with the Blue valve and green mainspring) and some say a tight bored low porting barrel which is only for if you want the absolute best efficency i use the boomstick which makes my gun a tad less efficent than a Lapco or AKA Javelin but its like i all ready stated sooo quiet.
If you want to get better efficency, better consistency which leads to a bit better long range accuracy and if you play wood ball and want to make youre gun soo quiet that friends cant hear you from about 30 yards away get this with an AKA bolt, Good high flow reg(AKA Sidewinder or MacDev Gladiator for Nitro, Palmers Stabilizer for Co2) and a good spring kit (MaddMan)
