Helldivers 2 R-63 Diligence Guide: Best Builds & Uses

The R-63 Diligence is one of those weapons that stands out not because of flashy gimmicks, but because it consistently rewards patience and precision. Sitting in the Marksman Rifle category, it offers high-damage, light-armor-penetrating shots that excel in medium-to-long-range combat. For players who prefer carefully placed shots over spray-and-pray chaos, the Diligence feels right at home.

Attachments & Customization

The Diligence shines with its flexible attachment pool. Players can lean into stability, ergonomics, or precision optics depending on their playstyle:

• Optics: From the standard 25m iron sight to a 4x combat scope, the rifle adapts easily to close or long-range situations. Reflex and holographic sights offer quicker target acquisition, while the 1.5x tube red dot balances range and speed.
• Muzzles: Muzzle brake and compensator options help reduce recoil, though at the cost of ergonomics.
• Underbarrels: Vertical and angled foregrips reduce recoil and sway, while laser sight combos provide better accuracy in hectic firefights.

Players experimenting with different builds often find that the Diligence rewards comfort more than raw numbers—set it up to feel natural for your engagements.

If you’re looking to make the most of the R-63 Diligence, experimenting with attachments is key. Comfort and personal preference often matter more than raw stats, so don’t be afraid to test different sights, muzzles, and grips until the rifle feels right in your hands. And since unlocking this weapon requires Medals, it’s worth planning your Warbond progress carefully—or simply choose to buy helldivers 2 medals if you want quicker access to powerful gear like the Diligence.

Tactical Use

Where the Diligence thrives is in precision play. Against lightly armored Automatons, it can reliably drop enemies with a single headshot. Devastators, in particular, can be dispatched in one clean hit to the head, making this rifle a powerful counter-sniper tool.

Against Terminids, however, the story changes. Their sheer numbers and prevalence of medium armor at higher difficulties make the Diligence less effective. You can still make it work, but you'll need to rely on teammates for crowd control while you surgically eliminate priority targets.

In short, the Diligence rewards squads that give their marksman time and cover to operate. If you're accurate, you'll always be valuable to your team.

Summary

The R-63 Diligence isn't for everyone. Players who crave full-auto chaos or heavy armor penetration will find it limiting. But for those who value control, pacing, and the satisfaction of landing decisive shots, this rifle becomes one of the most rewarding tools in the Helldivers 2 arsenal. Unlocking it early with just 8 Medals feels like a bargain for such a dependable marksman rifle.

The R-63 Diligence is a marksman rifle that specializes in high-damage, light-armor-penetrating shots. It performs best against Automatons and lightly armored targets, with strong customization options to suit a variety of engagement ranges. While less effective against swarms and heavily armored foes, its precision-focused design makes it a reliable choice for skilled marksmen.
