Mastering the R-63 Diligence in Helldivers 2 – Best Builds and Battlefield Uses

When it comes to precision rifles in Helldivers 2, few weapons strike a balance between range, power, and control like the R-63 Diligence. This marksman rifle is a favorite among veteran players who prefer steady aim and high-impact shots over chaotic spray fire. In this Helldivers 2 R-63 Diligence Guide: Best Builds & Uses, we’ll break down what makes this rifle special, how to maximize its potential, and which loadouts make it shine on the battlefield.

What Makes the R-63 Diligence Stand Out

The R-63 Diligence is a semi-automatic designated marksman rifle designed for medium-to-long-range engagements. Its biggest strengths lie in its accuracy, consistency, and versatility—traits that make it deadly in the hands of a player who values precision. Each shot packs enough punch to drop light and medium enemies with well-placed hits, making it an ideal weapon for clearing out groups of Bugs or Bots from a safe distance.

However, it’s not without its limitations. The R-63 struggles in close-quarters combat where automatic weapons like SMGs or shotguns dominate. It also has a slower rate of fire and smaller magazine, meaning you’ll need to make each bullet count.

Best Builds for the R-63 Diligence

While the Helldivers 2 R-63 Diligence Guide: Best Builds & Uses can vary depending on your playstyle, there are a few key loadouts that consistently perform well across missions.

1. Precision Scout Build

• Primary: R-63 Diligence

• Secondary: P-19 Redeemer

• Stratagems: Eagle Airstrike, Orbital Precision Strike, Supply Pack, Guard Dog Rover

• Armor Type: Light or Medium (Mobility Focus)

This setup favors players who prefer to pick off enemies from afar and stay mobile. The R-63 handles ranged threats, while the Redeemer covers you when enemies close in. Orbital and Eagle strikes provide a backup for crowd control when your position is compromised.

2. Defensive Marksman Build

• Primary: R-63 Diligence

• Secondary: GP-31 Grenade Pistol

• Stratagems: Shield Generator Pack, Mortar Sentry, Resupply, Orbital Gatling Barrage

• Armor Type: Medium or Heavy

This loadout is built for holding ground. The Shield Pack and Mortar Sentry provide area control, while the Diligence allows you to take out enemies approaching from a distance. It’s a great setup for missions that require defending objectives or extraction points.

3. Support Sharpshooter Build

• Primary: R-63 Diligence

• Secondary: LAS-5 Scythe

• Stratagems: Resupply, EMS Mortar Sentry, Orbital Railcannon Strike, Supply Pack

• Armor Type: Medium

This build is ideal for supporting teammates by thinning out enemy lines before they engage. The Railcannon Strike can eliminate armored threats instantly, and the LAS-5 ensures you’re never helpless when your rifle runs dry.

Best Uses and Combat Tips

The R-63 Diligence excels in open environments where you can take advantage of its superior range. When fighting Terminids, aim for weak points like heads or joints to maximize damage output. Against Automatons, focus on targeting sensors or power cores.

A crucial tip for Diligence users: pace your shots. The weapon’s recoil can throw off your follow-up aim if fired too quickly. Tap fire, reposition, and always maintain situational awareness to avoid being flanked.

Pairing the R-63 with a teammate who uses heavy firepower, such as an autocannon or flamethrower, can also create a balanced duo—precision and suppression working hand in hand.

In Helldivers 2, the R-63 Diligence is more than just a marksman rifle—it’s a tool for disciplined sharpshooters who value accuracy and tactical positioning. While it won’t suit every player or mission, those who master its rhythm will find it to be one of the most rewarding weapons in the game.

Whether you’re taking on hordes of Bugs or dismantling Automaton patrols, this Helldivers 2 R-63 Diligence Guide: Best Builds & Uses should help you fine-tune your strategy and dominate from a distance.
