ever thought of just leaving it at that RoF?
not all light machine guns are MG42's, my HK11 doesnt have a drum mag yet so i like the mag to last me atleast 10 seconds.
theres 2 things to remember when being an LMG:
1) people will duck and cover wether theres 5 BBs hitting the tree or 50; as long as its consistently hitting their tree.
2) LMGs dont kill people, greandes and rifleman kill people.
but if thats the way you want to go, you'll need a reinforced piston, reinforced v2 gearbox (or else!

and a silent piston head
as for a battery, the big difference ive found is in Mah. my 8.4v 3000Mah large fires faster than my 8.4v 1200mah mini, and my 9.6v 1400mah mini fires a tad bit slower. i recommend a nice juicy 8.4v 4200Mah battery
