Um.. what? I use a lonex spiral bevel on mine no problem...It also puts a lot of stress on your gearbox.
Furthermore, it means that you are unable to use the Lonex Spiral Gear set as you need to pair a dual sector gear with normal gears. For most dual sector gears these are either 18:! or 16:! gears.
Siegtech does produce 12:1 and 10:1 dual sector gears.
I've used a gate warfet, and while I've had trigger issues, I'm going to attribute that to the gun, not the mosfet. It does have a rate of fire control as well, which is helpful for if you're struggling with engaging your cutoff lever.Best pre-cocking mosfet.
