Delta Force PKM Bullpup Kit and HVK Binary Stock Kit: How to Unlock

Delta Force PKM Bullpup Kit and the HVK Binary Stock Kit are two of Aurora’s limited-time Haavk attachments. Both arrived with the November 10 update, but the way you obtain them depends on whether you are playing Operations or Warfare. The event uses separate unlock routes for Operations and Warfare.

The event ends November 17, 2026. The quickest route depends on your mode: Operations has an Auction House or crate drop, while Warfare has Armory missions.

How to get the Delta Force PKM Bullpup Kit in Operations

In Operations, the Delta Force PKM Bullpup Kit and HVK Binary Stock Kit can be bought from the Auction House or found as rare drops in Large Weapon Crates. Those are the two routes listed in Garena’s event notice.

Start by checking the Auction House for the specific attachment name rather than searching for a general Haavk item. Prices vary between Auction House listings. If the market listing is missing or too expensive, Large Weapon Crates are the alternative named in the official event notice.

Large Weapon Crates have only a low chance of dropping the parts, so don’t bank on finding one in a single run. Treat the crate as an opportunity during your normal extraction route, not a promised reward. Remember that finding a valuable item in Operations is only part of the job; you still have to get it out safely.

How to unlock the HVK Binary Trigger Stock Kit in Warfare

The Warfare version of the Haavk Military Attachments event uses a different instruction: open the Armory and complete the relevant missions to unlock the new attachments. Both attachments have missions in Warfare, with their current objectives shown in the Armory.

Open the Armory and look for the time-limited Haavk attachment challenges, then read the objective shown for the item you want. If you are in Operations and cannot see the same challenge, that does not mean the update is broken; the two mode notices explain different acquisition methods.

Choose the Armory mission for the attachment you want, complete its objective, then claim the reward if the game asks you to.

Delta Force PKM Bullpup Kit vs HVK Binary Stock Kit

The Delta Force PKM Bullpup Kit is made for the PKM General Machine Gun. The other kit’s full name is the SR-25 Marksman Rifle HVK Binary Trigger Stock Kit. Despite the event grouping, these attachments are for different weapons and should not be treated as interchangeable. Garena’s full Aurora patch notes list both sets of stat changes:

Attachment	Mode	Control	Stability	Accuracy	Handling	Special effect
PKM Bullpup Kit	Operations / Warfare	-4	+6	+16	+12	Removes trigger delay
SR-25 HVK Binary Trigger Stock Kit	Operations	+8	+3	-12	+3	Special firing mode
SR-25 HVK Binary Trigger Stock Kit	Warfare	+7	+2	-12	+2	Special firing mode

The Delta Force PKM Bullpup Kit makes a clear trade-off: it loses four Control points, but gains Stability, Accuracy and Handling, and removes the weapon’s trigger delay. The SR-25 stock instead increases Control and adds a special firing mode while reducing Accuracy by twelve points. The Warfare values for the stock differ slightly from Operations.

Before spending Tekniq Alloys, use the weapon customization screen to inspect compatibility and the resulting stat changes. A kit can look attractive in an event banner but still be a poor fit for a particular loadout. Compare the weapon’s stats before and after fitting the kit, then try it in a match.

The Delta Force PKM Bullpup Kit is also not the older HVK Whirlwind Enhanced Gas Block. That earlier attachment has its own guide and unlock conditions. The similar Haavk branding is an easy way to end up reading instructions for the wrong item.

When the Aurora Haavk attachment event ends

Garena lists the Haavk Military Attachments event as running from November 10 through November 17, 2026. The event notice does not provide an unambiguous UK closing hour, so use the countdown displayed in your own client for the final cutoff rather than relying on a guessed midnight conversion.

November 17 is the event deadline. The notice does not say existing attachments will be deleted then, but it also doesn’t promise the same unlock routes afterwards. Obtain and claim anything you want while the listed event is active.

If the challenge is absent, check the current game version first. The Aurora rollout was delivered without planned downtime, and the publisher recommends restarting the game when new content is missing. Then confirm you are in the correct mode and opening the appropriate menu.

Is the Delta Force PKM Bullpup Kit worth pursuing?

If you already use the PKM, the Delta Force PKM Bullpup Kit is worth testing before the event expires. The important question is whether its actual stat trade-offs improve the way you use that weapon. Check the in-game stat changes rather than relying on a claimed best-in-slot build.

If you are collecting Haavk hardware rather than changing a current build, the Operations Auction House and Large Weapon Crate options are more relevant than a Warfare mission checklist. Players concentrating on Warfare should go straight to the Armory instead. That is the simplest way to avoid wasting matches on an objective that belongs to another mode.

The Delta Force PKM Bullpup Kit changes the PKM’s handling quite substantially, but you’ll have to decide whether losing Control suits your build. The same applies to the SR-25’s HVK Binary Trigger Stock Kit: a new firing mode is valuable only if it suits your playstyle. The November 17 event window is the time-sensitive part, so check the relevant mode’s unlock route before it ends.
