Under-barrel grenade launchers represent one of the most powerful S.T.A.L.K.E.R. 2 weapon modifications, transforming standard rifles into devastating area-effect platforms. Many operators encounter operational challenges when first deploying these systems due to unfamiliar control schemes and ammunition scarcity. This comprehensive manual covers acquisition protocols, installation procedures, and tactical employment strategies for maximizing your combat effectiveness in the Zone.
How to switch to grenade launcher mode in Stalker 2
When your weapon system includes an installed launcher module, initiate the radial weapon interface by pressing Tab. From this configuration menu, select the C key to toggle between primary firearm and secondary launcher functionality. The weapon will visibly reconfigure in your hands, indicating successful mode transition. This operational switch functions identically to alternating between semi-automatic and full-auto firing configurations.
For rapid response scenarios, you can maintain pressure on the B key to bypass the radial interface entirely, enabling immediate access to your explosive capabilities. Critical reminder: verify ammunition status before engagement – the system will refuse to discharge without proper ordnance loaded.
How to install under-barrel grenade launchers in Stalker 2
The Zone features two primary grenade launcher systems: the GP-25 and advanced One-O-Three models. Both configurations require professional installation at certified technician stations. Each variant maintains exclusive compatibility with specific rifle platforms, creating strategic considerations for your loadout configuration. Note that specialized ammunition remains exceptionally scarce throughout trading networks and carries premium pricing structures.
- GP-25 — exclusive mounting capability on AKM-74S platforms only. Operational requirement: Vog-25 projectile cartridges.
- One-O-Three — compatible integration with AR416, Kharod, or the GP37 rifle systems. Mission requirement: HEDP high-explosive dual-purpose rounds.
When possessing an unattached launcher component, simply activate the equipment and perform drag-and-drop attachment to your primary weapon. Alternatively, employ right-click functionality on the grenade launcher inventory item to access the contextual installation menu.

Where to find under-barrel grenade launchers in Stalker 2
Multiple acquisition pathways exist for obtaining these powerful weapon enhancements. The most accessible early-game method involves securing the Drowned modified rifle system. This weapon resides within the Garbage territory as part of a compact mission involving an operative designated Boo. This character positions himself adjacent to the Slag Heap installation while lamenting his misplaced firearm. Accept his assistance request and retrieve the equipment. The rifle placement situates directly beneath his standing position. Retain this modified platform for personal deployment – Drowned constitutes a specialized AKM-74S variant featuring pre-installed grenade launcher capability.
Should conventional acquisition methods prove unsatisfactory while maintaining grenade launcher requirements, navigate eastward from Slag Heap. You’ll encounter a position labeled Intercom Tower. Access the compact masonry structure positioned to the tower’s starboard side.
Within this location rests a secured container featuring digital keypad authentication. The access sequence is 030794. Inside awaits a secondary containment unit housing the GP-25 under-barrel grenade launcher assembly. Important operational note: the attachment module arrives without accompanying ammunition. Potential procurement opportunities may emerge at the Cement Factory complex northern location, though availability remains uncertain.

Combat Optimization and Strategic Employment
Mastering grenade launcher deployment requires understanding optimal engagement scenarios and ammunition conservation techniques. These systems excel against concentrated enemy formations, fortified positions, and heavily armored targets. The substantial explosive yield creates area denial capabilities and psychological impact beyond mere ballistic damage.
Critical mistake avoidance: never engage without confirmed target acquisition due to limited ammunition reserves. Advanced operators recommend reserving launcher deployment for high-value targets where conventional firearms prove insufficient. The trajectory arc demands practice – utilize the Weapons Unlock guide for additional combat proficiency development.
