Just a little something I threw together in the past couple hours. It doesn’t change anything, but I figured it’d be useful to see why variants do what the do and what is used to do what they do.

DISCLAIMER : ‘Gun Sway’ and scope/ sight sway are unrelated.

Preliminary Analysis

Inter-class variants:

Factory, Low Weight, and Infantry variants share the same modifiers: Spread and Recoil decrease. This was pretty well known, however
1.) not all weapon types are strictly limited to these two benefits and
2.) the multipliers for these benefits differ from weapon class to weapon class, i.e.
3.) Factory SLRs only get spread/ recoil decrease, while MGs get spread increase bonuses while ADS as well (they get Bipods as well, but that’s not applicable here)
4.) SLRs have separate spread/ recoil decrease values from MGs

Trench is fairly straightforward with minor differences here and there, namely the inclusion or exclusion of spread decrease (in the case of Scout) or Hip spread increase (in the cases of Medic and Support).

Storm benefits and even the specific values are largely universal. The only notable shift from this grouping is the Mondragon Storm.

Optical variants share one common factor: a minimum spread ADS stationary and moving multiplier (0.75x) provided by the Heavy Barrel. Other than that, it depends on the class of weapon.

Class specific variants (ones worth noting):

SLRs -

Sweeper and Extended in the SLR category use Compensator and Ergo Grip modifiers to improve Hip spread increase and vertical recoil. Essentially, they do the same things. The difference is the Sweeper’s full auto capability and the Extended’s increased ammo capacity.

Sniper and Marksman within the SLRs use a type of Heavy Barrel (HBar, No Moving ) that doesn’t award shooting while moving in any capacity; only 0.667x improvement while ADS stationary as opposed to the traditional HBar’s 0.75x ADS stationary and moving. Naturally, stand perfectly still to maximize accuracy.

SMGs -

The MP18 Experimental uses the HBar, No Moving 0.667x modifier rather than the traditional HBar. This isn’t new information per se, but interesting nonetheless.

MGs -

Here’s the juicy part.

Low Weight 's common denominators are identical values of spread/ recoil decrease, but nearly each one uses a distict modifier to diffentiate ADS spread increase. They all use the same Bipod.

Telescopic s use the HBar, No Moving modifier just like the aforementioned SLR Sniper/ Marksman and SMG Experimental. But they each get varying modifiers for ADS spread increase/ decrease and Bipod spread increase/ decrease. Apart from the Bipod spread increase/ decrease these extremely specific Bipods are no different than the standard MG Bipod.

Optical . Not exactly class specific in terms of the variant, but it does a whole lot more than your typical SLR or SMG Optical. A single modifier called ‘LMG Optical 6’ dictates ADS spread increase/ decrease and Hip spread increase/ decrease. Additionally, it uses an ultra specific modifier for Hrecoil at 0.88x.
