Good SA58 para mods [Not For Beginners]
My mods for the SA58 Para are the Long Range Barrel , Trigger , Grip (Sorry for english)
Long range : Preserves damage from long range.[Damage not decreased from longer range]
Trigger : Improves single fire accuracy but decreases spray accuracy[Single fire only]
Grip : Give stability [Always good]
Enjoy!

Reinforced is better because the para's range is already really good. There are rarely any situations you would actually need that extra range compared to the close quarters combat fights where you would need the extra damage.
OPINION, reinforcement rifling barrel have more bloom and recoil than LRG, and I do oftenly headshot OHK on people at 20 meter and less.
TRAIN YOUR HEADSHOT OHK IN AI CANON (easy) because they barely move. Dont mind if you lose the game because it dont mess your ratio or win and loss.
