The 1500 round box mag has a matrix high speed motor installed so it can keep up with running a 11.1 lipo. The 2500 round mag is stock. Internal upgrades: Lonex Titan A2 motor M120 spring SHS steel tooth piston with AoE correction Brand new trigger switch Wired to deans Everything else is stock Includes barrel extension and Noveske sound amplifier.
