i have a few agm m4's and id like to do a dual sector gear in one of em. i understand you dont want a barrel length longer than 360mm, so if i add a nice motor like a lonex A1 some ceramic brgs do a shim job, throw a nice spring in there, prob some siegtech gears, piston and cyl and head should be good to go yes? gun should scream right? out of the many guns i have id like to try one of these gears. i am thinking its not any worse than adding a standard gearset just shoots a hell of alot faster even if i didnt change the spring. figure ill have a good batt too. dual sector gear means double the rate of fire right?
