UPDATE
Performed the following mods:
Sanded front of tappet plate, heated and bent for better alignment
Reshimmed hop up unit, using cardstock and O-rings
Relubricated hop up unit
Installed the following:
SHS Steel Cylinder
Prometheus Metal Piston Head
Modify 18:1 Gear Set
Modify Moundless Hop Up Rubber
Prometheus Bridge Tensioner
Chronoed today at Toronto Airsoft, same MadBull M120 and .2 Bastards
High: 455.7 FPS
Low: 455.1 FPS
Drops to 448 FPS with hop up dialed in.
I've never seen a gun chrono so consistently before, I guess I finally got that perfect air seal. I always thought +- 1 or 2 FPS was good, but I guess +- 0.3 is my new goal for the rest of my guns.
Current Internal Setup:
Lonex Enhanced Aluminum Cylinder head
Lonex Air Seal Nozzle
Lonex Hop Up Unit
Madbull M120 Spring
Modify Gear Set
Modify Quantum Piston
Modify Bearing Spring Guide
Modify Moundless Hop Up Sleeve
Prometheus Metal Piston Head with Bearings
Prometheus Soft Bridge Tensioner
Prometheus 6.03mm 550mm Tightbore Barrel
SHS Full Cylinder
