With the temp hitting +11 yesterday, I went out to our teams practice field with some team mates and we ranged several guns.
With the stock barrel and hop up, my MK46 was able to consistently hit a team mate at 230 ft with short bursts despite a cross wind, and if I stretched it, able to lob out to 250 ft inaccurately. This was not measured with a tape, but paced out so the distance may be a little off, suffice to say over 200 ft easily.
With baseline testing completed I'm going to add the 6.03 TBB, Bullgear Hop Up, & Flat hop the assembly to try and hit 275-300 ft semi-accurately.

The whirring noise referenced in post #5 is also back, but much better. Assuming this is caused by the active braking on the mosfet I wired in a rectifier diode (1N4007 - although any 1N400x diode should work) which forces electrons to move only in one direction. In other words this is like a one-way valve for wiring and will prevent the active brake from turning the motor in the gearbox. We'll see if this solves this problem.
