Damage is high at 106, bringing you up to ~111 and letting you two shot headshot with some minor damage boosting skills.
RPM is average at 675, same as in MW2022.

Ammo capacity starts out with 20 round Lancer mags and 4 total magazines for a total of 80 rounds. Ammo pickup is 2-4.5 at base, which should be comfortable so as long as you are careful with your aim.

Stability is above average for a battle rifle at 52, with kick values about on par with the CAR4/M4A1, resulting in a rifle that should be comfortable to keep controlled. This is to account for the True Velocity recoil mitigation system that David Stouffer (spelling?) was boasting that their RM277 in 6.8x51mm TVCM has the same recoil impulse as a M4A1 in 5.56x45mm NATO.

(Look I know that last part is marketing speak from True Velocity and from Task and Purpose of all sources, but considering that RM277 information isnt as widespread as the Spear and I cant just call up True Velocity to test fire both an M4A1 and a RM277, I make do with the information I got).

Accuracy at 52 is average for most rifles and subpar for a battle rifle. I am aiming for most RM277 builds to land in the mid 80s range, with only specific marksman/lengthy builds achieving perfect accuracy at the cost of your stability.

This might seem incredibly odd considering the RM277 has a fairly long barrel length at 19inches, longer than the MCX Spear's 13inch barrel and the RM277 can go even longer with the NGSW-AR barrel. However, the slightly subpar accuracy is a gameplay concession made to differentiate the RM277 from other battle rifles/my MCX Spear. Whereas other battle rifles are precise but have high kick, the RM277 has low kick but is (relatively) imprecise.

The RM277's concealment is rather good for a battle rifle at a base of 13, considering its bullpup nature. The max concealment I'm aiming for with the RM277 is around ~20 concealment, albeit at the cost of your accuracy.

The only unique mod in the list is the 6.8x51mm WRATH conversion, which grants you access to piercing armor/enemies/walls, but not shields. No, you are reading the list of added piercings correctly, I purposely excluded shield piercing.

This is to make fun of MW2022's strange tendency to make legally distinct versions of everything, even though I'd assume most real weapon manufacturers would love to have some product placement in one of the most popular FPSes in the world. So if you have bootleg 6.8x51mm FURY, you also get a bootleg armor piercing effect. This also isn't mentioning the strange mistake of Infinity Ward chambering the offbrand SIG Sauer cartridge in the RM277, when the NGSW weapons and their respective calibers are supposed to be a package deal?

Gameplay wise, the WRATH ammo is just a meme ammo made to make fun of Infinity Ward's strange mistakes. I dont actually expect people to use it, though I am sure some clever players will find some way to abuse the extra piercing types added.
