- Recoil Control is Key: If you find yourself struggling to keep your shots on target, focus on upgrades that reduce recoil, like the 'Additional Return Spring' or 'Bolt Hammer Compensator'.
- Accuracy Matters: For those longer engagements, boosting accuracy with upgrades like the 'Addition Of A Balancing Element' or the 'Change To A Roller System' will make a huge difference.
- Fire Rate vs. Handling: Decide if you want to burn through ammo faster with increased fire rate or have a more responsive weapon with better handling. Sometimes a balance is best!
- Magazine Size: Don't underestimate the 'Increased Magazine Capacity'. More bullets mean fewer reloads in a firefight, which can save your life.
- Calibre Change: The 'Change Of Calibre To 9x18' is a big investment, but 9x18 ammo is generally more common, so it might be worth it for sustained combat if you're running low on other types.
