Future police rifle, secret forces rifle, or impulse rifle.
I went with the FPR. But then I've got a maxed out Champion Peacemaker to alternate with.
The SFR is probably the best option overall, but you'll have to spend quite a bit to upgrade it.
Impulse and Mega are good choices as well, but if you want and use the accuracy of a 4x, their "Area-damage", will not only rob you of the ability to headshot, but also make them more sensitive to narrow shooting angles.
If mobility is not an issue, the FPR is Nasty! High fire rate, large capacity and devastating accuracy, with or without the scope.
If mobility is what has put you off the MgSg, the SFR is the way to go, if you have also been missing long range performance and a scope.
Otherwise, take a look at the Adamant Laser Cannon. No scope, but mobility 85, and insane accuracy and fire rate. Not great for "spray-and-pray", as it runs out of ammo in seconds. But take a couple of seconds to aim, and you'll get the kill in a heartbeat (two to five if you're excited)! ;-)
If you can land headshots with the champion peacemaker
At medium to long range, the ChPM is more of a fire support/kill assist type weapon. Best used in team battles where your mates can finish the job. Quick and clean kills at range are better accomplished with scoped weaponry. But it is very easy to score one or several hits, and the 150 round capacity allows for quite a bit of continuous fire.
At close to medium range though, it's a different ball game.
When he's flashing red;
raise your aim, if he ain't dead,
you will hit the head.
It turned into a haiku... ;-)
Just use a fully upgraded "Predator" its upgrades are in discount on Realistic Mode Brawls, it kills a max armor person with 2-3 Headshots in close range like Pool Party corridors, but in the outside it is trash.
Does the Predator get an "Up" along the way? Like an improved Mobility and/or Capacity, like some other guns do...
Looking for a good shotgun Primary and it does look good, both visually and stats-wise!
Mag exents to 20 capacity and mobility is upgrading and effecinty(it takes 2-3 headshots in short range)
Or Mega Gun or İmpulse Rifle
To get back to the OP: Wait for sweet Clan weapons or Battle Pass weapons and spend your savings elsewhere.
Or just get the FPR, you won't be disappointed. 3-4 kills, at range, without even using the scope, is not an uncommon result from emptying a single magazine! Mobility is low and reloads take forever, but if you kill everyone heading your way before they get close, while moving around enough to be hard to snipe, you can reload in peace!
And get a *** Storm Trooper Cape to go with it!
It's evil. :-D
