Source review — 10 November 2026: This is an original-game loadout from the dated guide below. Accessible source pages confirm the listed weapon attachment names. Perks and equipment retain their original dated attribution; the source review does not imply hands-on testing or a fresh balance-patch analysis.
The RK5 is the three-round burst pistol of Black Ops III, with a fast burst cycle, unlocked at rank 22. GameRant uses it as the backup in its Man-O-War and M8A7 classes, for tight spots and during reloads. The verdict: it is the sidearm to pick for a rifle class, and it needs little investment. Stats come from an undated sheet.
Best RK5 loadout
No major guide publishes a build for this gun, so this is our suggested setup from its available attachments. GameRant lists no attachments on its RK5 at all, and one player's 2016 camo guide ran bare pistols or mag attachments.
| Slot | Pick | What it does |
|---|---|---|
| Attachment | Fast Mags | Reload faster |
Why this build works
Marvel4's sheet lists 35 damage out to 200 range units, 29 to 500, 22 to 750 and 19 past that, at 775 RPM. That is three hits to 200, four to 500 and five to 750. The sheet adds that without Dual Wield, the first two rounds of each burst fire at the same time. Reload is 1.5 seconds with rounds left and 1.85 empty, and the 15-round magazine goes to 21 with Extended Mag.
A sidearm is mainly there to fill the moment your rifle is empty, so one attachment is enough. Spending fewer points leaves more for your primary class.
How to play it
Switch to it instead of reloading a slow primary at close range. The sheet says switching to a handgun uses quick drop and quick raise. Its damage falls fast with distance, so use it only inside short range.
Alternative setups
Dan Fasulo's camo tips post (17 March 2016) says Dual Wield raises damage output and is easier to manage on the RK5 and L-CAR 9 than on the semi-auto MR6. The site says you can't aim down the sight with it equipped, and the sheet lists a Dual Wield fire rate of 654 RPM.
Unlock notes
Unlocks at rank 22, according to The Black Ops III.
