1. Heavy Sniper Mk II: The Long-Range Destroyer
This powerhouse remains unmatched for taking out targets from distance. With explosive rounds available through bunker research, you can obliterate vehicles and armored targets in seconds. The thermal scope makes night missions a breeze, while the suppressor keeps you off the radar during stealth operations.
Pro tip: Upgrade from the base version for $165,375 at any weapon workshop.
2. Special Carbine Mk II: Your Reliable Workhorse
Need one weapon that handles everything? This assault rifle delivers exceptional accuracy with minimal recoil. Its versatile ammo options and consistent damage output make it perfect for heists where precision matters. Whether you’re storming a facility or defending your position, this gun never lets you down.
3. Combat MG Mk II: The Crowd Controller
When you’re facing waves of enemies or holding down a position, nothing beats the Combat MG Mk II. Its massive 200-round magazine and rapid fire rate turn you into a one-person army. The surprisingly quick reload time keeps you in the fight longer, making it ideal for intense Freemode battles.
4. Up-n-Atomizer: The Problem Solver
This ray gun-style weapon fires energy coils that send NPCs, players, and vehicles flying. Stuck vehicle? Zap it. Chase mission gone wrong? Blast the target’s car. The beauty lies in its cooldown-based system—no ammo shopping required. It’s quirky, powerful, and endlessly useful.
5. Compact Grenade Launcher: Pocket-Sized Destruction
Don’t let the name fool you—this handheld launcher packs serious punch. Perfect for turning enemy vehicles into scrap metal, it offers better mobility than the standard grenade launcher. The default version handles most situations, though upgrades through your weapon workshop unlock even more devastating potential.
Building Your Ultimate Arsenal
Visit Ammu-Nation stores across Los Santos to purchase these weapons. For Mk II variants, you’ll need access to a weapon workshop at your bunker, arcade, or mobile operations center.

Smart Weapon Management
Remember to customize your weapon wheel using a gun locker. This prevents scrolling through dozens of weapons during heated firefights. Focus on keeping just one top-tier weapon per category equipped.
Pair these weapons with armored vehicles like the Karin Kuruma for maximum effectiveness. The combination of firepower and protection makes you nearly unstoppable in most scenarios.
