ROB RUN Best Guns Tier List
The RC 5.56 Mk3 is our best overall gun in ROB RUN thanks to its combination of 16 damage, 667 RPM, and a 50-round magazine. For players prioritizing raw firing speed, the AP Scalar Mk3 stands out at 1,000 RPM, while the LM 249 Mk2 offers an enormous 200-round magazine.
We've ranked all 17 weapon families below using their strongest documented variants, considering damage output, ammunition capacity, and overall practicality. These rankings are based on published weapon stats rather than claimed personal combat testing.
| Tier | Weapon | Main Strength |
|---|---|---|
| S | RC 5.56 Mk3 | Best overall balance |
| S | AP Scalar Mk3 | Fastest firing rate |
| S | SR Reaper Mk3 | High automatic damage output |
| S | LM 249 Mk2 | Largest magazine |
| S | TAG-12K Mk3 | Highest shotgun firing rate |
| A | STAR-H Mk3 | Hard-hitting automatic rifle |
| A | JP-7 Mk3 | Fast, balanced SMG |
| A | PDW90 | 50-round SMG capacity |
| A | ORDR-12 Mk3 | Strong shotgun alternative |
| A | KL-545 Mk3 | Excellent value assault rifle |
| B | DRM-14 Mk3 | High damage per shot |
| B | CB45 Mk3 | 40-round magazine |
| B | MC-10 Mk3 | Affordable automatic weapon |
| B | Vulture 50 | Highest pistol damage |
| B | Harris 500 Mk3 | Accessible shotgun option |
| B | LBR-44 | Powerful individual pistol shots |
| C | DP-9 | Cheap starter pistol |
S-tier weapons offer the strongest overall statistical advantages, while A-tier guns remain competitive alternatives. B-tier weapons have more noticeable limitations in fire rate, capacity, or versatility. The DP-9 sits in C-tier for overall firepower, although its low price still makes it useful early on.
Best Guns to Use in ROB RUN
RC 5.56 Mk3: Best Overall Gun
The RC 5.56 Mk3 combines 16 damage per shot with a firing rate of 667 RPM and 50 rounds per magazine. That makes it an excellent all-around choice, particularly when compared with weapons that sacrifice magazine capacity for faster shooting.
Its listed base value of $32,000 is another advantage. The RC 5.56 offers a strong combination of firepower and capacity without reaching the six-figure values of several other S-tier weapons.
AP Scalar Mk3: Best for Fire Rate
At 1,000 RPM, the AP Scalar has the highest listed firing rate in ROB RUN. Its 14 damage per shot translates to approximately 233 theoretical damage per second during uninterrupted firing, before accounting for accuracy, armor, damage falloff, or reloads.
The Mk3 also improves magazine capacity from 25 to 45 rounds. That's a substantial difference for a weapon that consumes ammunition so quickly.
The downside is its $115,000 base value, making it a significant investment compared with other automatic weapons.
LM 249 Mk2: Best for Sustained Fire
The LM 249 Mk2 stands apart because of its 200-round magazine. Combined with 18 damage and 706 RPM, it offers impressive firepower without the frequent reload interruptions associated with smaller magazines.
Its main statistical drawback is a five-second reload, while its $209,600 base value makes it the most expensive weapon in this comparison. I'd prioritize it for its massive ammunition capacity rather than assuming it's the most practical option for every player.
SR Reaper Mk3: Best High-Output Rifle Alternative
The SR Reaper Mk3 deals 17 damage at 750 RPM, giving it approximately 213 theoretical damage per second during continuous firing. Its 40-round magazine also provides twice the capacity of the Mk1 and Mk2 variants.
It's a strong alternative to the RC 5.56 if you favor higher damage output over magazine capacity and purchase value. The trade-off is substantial, with the SR Reaper carrying a $120,000 base value.
TAG-12K Mk3: Best Shotgun
The TAG-12K Mk3 fires eight pellets dealing 9 damage each, with a firing rate of 240 RPM and an eight-round magazine. That gives it the strongest combination of shotgun firing speed and capacity among the listed options.
However, shotgun damage figures depend on how many pellets connect. Its maximum listed damage per shell shouldn't be treated as guaranteed damage against every target or at every distance.
Best Budget Guns in ROB RUN
You don't need an S-tier firearm to get a worthwhile upgrade. Several cheaper weapons offer strong enough stats to make them attractive purchases before you can afford legendary or exotic equipment.
| Weapon | Base Value | Why Choose It? |
|---|---|---|
| DP-9 Mk1 | $300 | Cheapest starting option |
| MC-10 Mk1 | $3,500 | Low-cost automatic fire |
| CB45 Mk1 | $3,780 | Higher damage per shot than MC-10 |
| KL-545 Mk1 | $6,000 | 30-round assault rifle |
These are item base values, not guaranteed Black Market purchase prices. Check the actual cost and unlock requirements before buying.
Of these options, I'd choose the KL-545 as the strongest budget upgrade. Its 15 damage, 600 RPM, and 30-round magazine offer a useful combination at a much lower base value than most higher-tier rifles.
The MC-10 is another inexpensive option if you specifically want an automatic weapon. The DP-9 remains the easiest starting point when money is extremely limited, even though its 14-round magazine and 333 RPM place it well behind stronger firearms.
Are Higher Weapon Marks Better in ROB RUN?
Higher weapon marks don't automatically increase damage. Several Mk3 weapons retain exactly the same damage and fire rate as their earlier versions, with the main improvement coming from magazine capacity.
For example, the KL-545 increases from 30 rounds at Mk1 to 45 at Mk3, while the SR Reaper doubles its magazine from 20 to 40 rounds. Neither receives an increase to its listed damage per shot or RPM.
Other weapons show no differences in the supplied core stats between certain marks. All three PDW90 variants, for instance, have 13 damage, 857 RPM, and a 50-round magazine.
That distinction matters when choosing what to unlock or purchase. A higher mark may offer more ammunition before reloading, but it doesn't necessarily deliver more damage with each bullet.
For the strongest overall statistical package, the RC 5.56 Mk3 is our top recommendation. If budget isn't a concern, the AP Scalar Mk3 and SR Reaper Mk3 offer greater theoretical firing damage, while the LM 249 Mk2 provides unmatched magazine capacity. The best choice ultimately depends on whether you value damage output, fewer reloads, or affordability.
