I dont use grip cause i got enough faith in my own aiming skills. Plus it only helps accuracy right? Not too worried about that with a close range shot gun. and i could never trade scavenger pro for bling pro
i'd say that the holographic sight and fmj are a waste
holographic sight because it's a close range shotgun which means it's more effective fired from the hip rather than wasting time pulling up the sights and fmj a waste because how often will you use the shotgun to kill someone through a wall?
its up to you though however you wanna use it
try it out with a grip, scavenger pro, lightweight and steady aim though and see how it feels, if you dont like it go back to your original class but personally i believe mine is the perfect class for using the AA12..
you have the grip and steady aim combined to reduce the recoil nicely ( and the AA12 does have a lot of recoil), scavenger pro giving you what is essentially unlimited ammo which is very useful considering how fast the AA12 burns through it's ammo and lightweight is useful when you want to get up close and personal more quickly
