alright, so another little update for Carbines.
the M4 is my new favorite carbine for Conquest, Rush and sometimes TDM and DOM, provided i know my weakness and don't get into a CQ situation. accessories i am running right now are - Coyote RDS (until i unlock the Kobra RDS), Laser Sight, Flash Suppressor, Angled Grip.
i use the Kobra RDS and Green Laser Sight on every gun once i unlock them. i chose the Flash Suppressor over Heavy Barrel because it adds more Stability. i chose Angled Grip to help control first shot recoil and it drastically reduces it from 2.5 to 1.675.
the range on the M4 is 870 meters compared to the ACE 52's 600. the muzzle velocity on the M4 is 580 compared the ACE 52's 400. M4 beats it on reload time as well, 2.4 seconds with an empty mag and 1.85 with bullets left in the clip compared to 3.1 seconds with and empty mag and 2.3 seconds with bullets left in the clip.
the recoil model of the M4 is very similar to the M16A3 from BF3 while the ACE 52 is pretty much straight up with little to no left and right recoil.
the time to kill is very interesting as well. the M4 beats the ACE 52 in every range up to 90-95 meters. the only range that the ACE 52 had a better time to kill is between 36 and 45 meters. both guns almost even out in time to kill around 90 meters.
the M4 will take anywhere from 1-2 bullets more to kill but your firing three at a time, all of which usually land on target. it should take no more than 3 burst's to kill a person up to 95 meters. provided you hit your first 6 shots, it might only take 7, maybe 8.
the only thing is you need to get used to fast burst firing, but not to fast. if you pull the trigger for a second burst before the first burst finishes the gun won't fire that second burst. once you get used to getting your timing correct between trigger pulls the M4 is quite an amazing carbine, especially at range.
