Just to let you know that the FY71 absolutely destroys with Aim Enhance as the Power Module. I know some of you don't want to give up your Retriever lol but you have to check it out the guns is amazing.. high-damage, no recoil.
In case you don't think I'm worth listening to I currently have 3.72 KD and only play TIA so I don't boost by not playing the objective in Crash Site (although this is essential when playing with a group). My KD would be a lot higher but my brother has died so many times on my account I have to 30-0 in a game to just go from 3.72 to 3.73.
The gun is perfect. This is the setup I use;
Energy Transfer
Stealth Enhance
Aim Enhance
FY71 with extended mags and ironsights. I don't use suppressor.
I use ironsights for extra visibility (I don't have this big black frame and red dot covering a 1/3 of my screen) and due to the aim assist I cannot see any reason to use a reflex sights on any weapon except the SCAR (due to it's high muzzle flash) because it's so easy to aim on this game.. which is a good thing.
I don't use suppressor so that I can do more damage from medium to long distances. I find that I'm moving so fast throughout the map that going silenced makes little difference. Plus I love the sounds of unsilenced weapons especially the Scarab.
The reason I started using Aim Enhance with this setup is due to the FY71's high recoil. I was having to use it as a close range weapon as it was difficult to full-auto anyone from 20m+... here are three advantages of using Aim Enhance;
1) Less recoil = more hits and I mean a lot more! This obviously equates to more kills.
2) Improved Range = more kills with zero recoil at medium to long range allowing you to be more adaptive to any situation. Rather than keep having to get close you can shoot someone from almost any range with no recoil.
3) Save Ammo - As you tend to hit a lot more you will save a lot of time scrounging on the flow for weapons trying to find that 34.5623 degree sweet spot before you're allowed to pick another weapon up. You'll also be able to get more double/triple sprays. I was on Crash Site this morning and got a relentless with one clip and reloaded and killed a fifth but didn't get a Psycho

Again, I know nothing beats Retriever but if you like to use the FY71 then try this out and you will love it even more.. it's now my favourite weapon closely tied with the Scarab..
Happy Hunting
